The Straight Dope message board has a thread on "shrinklits" of movies. OK, well they're not rhyming like the original and excellent shrinklets. But they can still be funny.

IMHO, the shorter the better. Here's one of the shorter ones:

LEAVING LAS VEGAS

HE: I'm going to drink myself to death.
SHE: Okay.

The End.

And another:

American Pie

High School Senior Guys: Hey, we should all try to get laid before graduation!

*guys get laid*

So true.
