Lipstick's a solid at room temperature so it can't be that.

Ok, is it a type of cream?

It's by virtue of the fact that it's fully manual. Unlike most lenses made over the last decade, there's nothing digital or electronic in there, it's all moving parts that you can move yourself. So you will never not be able to focus with it or control the aperture. The downside is that you have to do those, and not the buttons on the camera, but to be honest, any photographer worth their salt does this anyway.

As for the second part, I'm not entirely sure what you'd be losing when mounting the Helios onto the M4/3rds. From a quick read through of the wiki page on that system, it would be appear that cropping occurs and a slight loss in image quality due to the sensor. I have underlined a few points of interest.

From the page:
Disadvantages of Micro Four Thirds compared with DSLRs
    The sensor is 35% smaller in area (2.0x crop factor) than APS-C (1.5x crop factor, or 1.6x for Canon-APS-C) sized sensors and 75% smaller (i.e. a quarter of the area) than a full frame sensor (1.0x crop factor) (35 mm equivalent), which can mean lower image quality when all other variables are the same. This might include poorer color transitions and more noise at equivalent ISO settings, especially in low light, when compared with the larger sensors.
    Due to the absence of a mirror and prism mechanism, there is no ability to use a through-the-lens optical viewfinder. A through-the-lens electronic viewfinder, an attachable optical viewfinder (similar to a rangefinder or TLR), or the universally supplied LCD screen can be used instead.
    A larger crop factor (2x multiplier versus APS-C's 1.5x) means greater depth-of-field for the same equivalent field of view and f/stop when compared with APS-C and especially full frame cameras. This can be a disadvantage when a photographer wants to blur a background, such as when shooting portraits.

Popularity with Adapted/Legacy Lenses
    Due to the short native flange distance, of the Micro Four Thirds System, the usage of adapted lenses from practically all formats has become widely popular.
    Because lenses can be used from old and abandoned camera systems, adapted lenses typically represent good value for the money.
    Adapters ranging from low to high quality are readily available for purchase online. Canon FD, Nikon F (G lenses require special adapters), MD/MC, Leica M, M42 Screw Mount, and C-mount Cine lenses to name a few are all easily adaptable to the Micro Four Thirds system with a glassless adapters resulting in no induced loss of light or sharpness.
    Due to the 2x crop factor of the Micro Four Thirds System however, most adapted glass from the 35mm film era and current DSLR lineups provide effective fields of view varying from normal to extreme telephoto. Wide angles are generally not practical for adapted use from both an image quality and value point of view.
    Some disadvantages of using older adapted lenses on micro four thirds sometimes slight losses in image quality. This is the result of placing high resolution demands on the center crop of decade old 35mm lenses. Therefore 100% crops from the lenses do not usually represent the same level of pixel-level sharpness as they would on their native formats.
    Another slight disadvantage of using adapted lenses can be size. By using a 35mm film lens, one would be using a lens that casts an image circle that is far larger than what is required by Micro Four Thirds Sensors.
    The main disadavantage of using adapted lenses however, is that focus is manual even with natively autofocus lenses. Full metering functionality is maintained however, as are some automated shooting modes (aperture priority).
    An advantage of wildlife shooters and birders in particular lies with the fact that old 35mm telephoto lenses become extreme telephotos due to the system's 2x crop factor.
    Overall, the ability to use adapted lenses gives Micro Four Thirds a great advantage in overall versatility and the practice has gained a somewhat cult following. Image samples can be found readily online, and in particular on the MU-43 adapted lenses forum.

Is it used in cooking?

I don't know... velcro? No, it can't be that, because that's not a representation of someone or something...and it does vary in size.
Crap.

Can it be folded and/or bended? (I'm aware that you said it could be posted in an envelope so...)

Yeah...well actually since they're already working, and working really hard because their society demands toil, then under these conditions, none of the children should technically have to train. All the kids who've grown up in the shitty districts should be shaped by the hard world around them, they should be practical, hard, fit, and have plenty of survival skills. That they don't and that some come across as wide-eyed bambis is, in my opinion, one of the failings of the film to set up a plausible universe (along with the absurd notion that a few 19th century societies each with 19th century technology can support a 22nd century society).

With regards to gladiatorial games, I'd like just to point that virtually all entertainment with violence mimics what the Romans did. Films and TV are our gladiatorial games, entertaining us with skill, blood, and drama (heroics, trickery, cowardice, pride, bravery etc). Because you can bet if the Romans could fake it like as well as we do then they'd have done it too.  The surpreme irony is a show like Spartacus, which is a bloodthirsty gladiatorial show about bloodthirsty gladiatorial games.

Supergirl looks like she's dressed in typical high fantasy elven garb, so I didn't think much of that one, same with Powergirl (it's the boots more than anything I suppose), but Psylocke and Elecktra work really well and fit in perfectly with their characters (i.e., they're dressed like ninjas).

So what was the internal varieties thing then? I think you should stick to yes/no answers 

I think it's time to admit I have a man crush on Kurt Russell. Fella has been awesome ever since I first saw him in Big Trouble in Little China.

Re-reading Blade of the Immortal, which is actually a manga with pictures and stuff, cuz I can't read. Seriously though, I read all day for my job (I'm a copyeditor by trade) so these last 5 years or so I find it a struggle to pick up and read a book. Which is actually more of a shame than you might think, because I love to read.

Blade of the Immortal, for what it's worth, is one of the finest comics you'll ever read and is a sprawling epic about an immortal ronin with, and this is the shocker, blades (yes, more than one!). So really the title is misleading. Why is it so great? Because the dialogue's poignant and funny, one moment it's ghastly dark and the next it's just really romantic, there's a fair amount of action, and the artwork is stunning in that it's very well staged and you can clearly see emotions on characters' faces, you can see what they're thinking. I bet if you read in its original Japanese, you could understand the gist of what was going on. In my experience, 99% of comic artists cannot draw expressions that go beyond 'I'm angry' or 'I'm attacking', which are usually drawn the same, and neutral.

I'd love to see some more Arnie films - Predator, Running Man and Total Recall being at the top of that list. And True Lies I guess, since it'll get you one step closer to doing the Complete Cameron Collection. Gotta catch em all etc.
