One that comes to mind right now is A fish called Wanda. It was probably the first movie I ever saw, and it was hilarious. Then, for 10 years for some reason I always stated it as the worst movie ever, but now that I saw it again I just laughed my arse off... It's great. Also, I liked Meet the parents, I almost wet myself while watching that.

I don't like Jim Carrey at all, I can't stand his acting, and I try to avoid any movie of his as best I can...
