The Incredibles is as good as Shrek IMO. Also Toy Story and its 2 sequels were very good, if they can be counted as "comedy".
I loved toy story as a kid but if i watched it now i probably wouldn't enjoy it that much apart from nostalgic reasons. Shrek and the incredibles, as you mentioned,i still find really good and get a laugh out of. Monsters INC is another good one. (tbh most Pixar films are brilliant)
