Yes Man.

I have never laughed so hard in my entire life. This has got to be one of his funniest movies. Zoey blahblah was kinda cute in this (her voice trips me out) but Jim Carey was at his funniest in this. There was a little chemistry between the two main characters - mostly he had some of the romantically funny lines in the entire movie. Definitely going to pick this up on dvd.
