What are good comedy movies for kids?

I'm 11 and these are some films i have seen: Planet 51, Night in the museum 1 and 2, Furry Vengeance, Diary of a Wimpy Kid, Pink Panther 1 and 2, How to Train Your Dragon, Pirates of the Caribbean 1,2,3 and 4 when it comes out (think it comes out on may 20th 2010)

Here is a good site to watch movies on for free and legally

Hope this helped
