Top Comedies of all time? That's a tough list...

Alright, so I decided I was going to do a top 10 or 15 list of comedies. The tough part about comedies is that it takes different elements to make different people laugh. So, while some people may find fart jokes entertaining (and who doesn't) some people like a more intellectual approach.

Obviously the list won't please everyone, but I'm gonna do my favorites. Here is where I need YOUR help. Every time I do a list, I always think of one later on that truly should've been on the list. So, what do you guys think should be on there? Is it hard to think of some? I know, it's not easy. But, instead of working, I was busy thinking of great comedies for a bit of a list. Don't worry, I worked a bit, too. So, here is a list of comedies that came to mind, to make your decision making a bit easier.

Thanks for the input.
