How about Grandma's Boy? "Don't judge me monkey." Love that movie! :WOOT:
Or anything from Kevin Smith including Clerks, Mallrats, Jay & Silent Bob Strike Back, & Clerks II.
Or Broken Lizzard movies? Super Troopers, Club Dred, & Beerfest.
40-yr old Virgin, Anchorman, Van Wilder, Waiting.
Here's one most people have probably never heard of. Kung Pow, Enter the Fist. If you've ever watched some of the old Kung Fu movies this one takes footage from old movies combined with new footage and spoofs the whole genre with voiceovers. Great movie if you're in the mood for something funny (funny like a clown).
Just a few of my faves. BTW, most of the above are even funnier when enjoyed with a few :cheers: . Sorry, root beer for you young whippersnappers. :wheelchair:
