Funniest improvised moment?

[JimmyGene]

I can't decide which I prefer; 'the most annoying sound in the world' from Dumb & Dumber or 'sorry wrong pocket' from The Mask.

What are your favourite improvised moments?

i absolutely love the screen tests from 'lemony Snickett'.....Jim totally improvises ...he's brilliant at improvising, he has such a sharp wit

Oh yeah! When he talks about milking the snakes the whole thing is hilarious.

I love all the out takes at the end of his funny films especially Liar Liar some hilarious moments.

I love ALL of them! He is the best at improvising! I have to say though my two favorites are the most annoying sound, and those things from series of unfortunate events! I agree those deleted scenes are hilarious! I love the one from Liar Liar where he has the paper and crumples it up, then say "a goose!"
