Anyone see Pandemonium? It's from the 80s. It's along the same lines of the Scary Moviespoofs of today. The movie had quite a few big stars in it, although I'm not sure if they were big stars upon release (Phil Hartman, Paul Reubens, Judge Reinhold.) Pretty sure Tom Smothers was pretty famous already, another cast member.
Rat Race omg, I loved the guy with the tongue piercing best! Hilarious movie!!
(Actually, I enjoy most anything with Seth Green.)
Sugar and Spice
Mrs. Doubtfire
My Big Fat Greek Wedding I usually don't like romantic comedies, but this one charmed me to the core!
The Chevy Chase Vacation movies
White Chicks
The House Bunny
All in all, the sillier=the better for me!
