MEAN GIRLS and SORORITY BOYS are both very funny, despite the way the posters make them both look like seat-filler pablum. MEAN GIRLS is a no-brainer now that Tina Fey's a thing, but I remember at the time being very surprised by how smart it was -- it's got a clear proto-30 ROCK sensibility.

I also love Hot Rod... but I also saw Rad more times than was healthy as a little kid.

no idea on what you do and don't know, but here's some (some classics, some randoms):

Young Frankenstein
Where the Buffalo Roam
Trading Places
Top Secret
Three Amigos
Repo Man
The Police Squad (TV show - pre Naked Gun movies)
Fish Called Wanda
Spinal Tap 
Fast Times at Ridgemont High (dated at this point, but still has some solid bits)
Brewster’s Millions

Splash.

Tootsie.

Project A-KO- it started life as part of the first anime porn series (Cream Lemon), but at some point in development they realized they had something special so they dropped the sex and made a great comedy. And, yes, it's named after Jackie Chan's Project A.

The Irresponsible Captain Tylor- If you like your science fiction with large space battles, you might like this TV series. A very zen 20 year old joins the space forces because he wants a pension, and ends up in command of a ship as a major war breaks out. Can doing nothing and surrendering often win the war? Or at least get the girls?

Six String Samurai- a low budget movie about a Buddy Holly look alike who is traveling through post-WW III and Russian occupied America to reach Vegas and become the new King now that Elvis is dead. Lots of sword fighting and general coolness.
