This is perhaps one of the funniest websites ever! It's called penny arcade. If you click on "archive" at the top and read a few of their comcis at random, you're bound to get a chuckel or two. They're pretty funny!
Here is a sample (be warned, it's a little profane. Inf act some of the comics are profane in general, like blood or cuss words):

I'm not a particular fan of PA, mostly due to said profanity, but I do quite enjoy the KH comic featuring Se-Pooh-roth. :P
Yeah, that was a good one! I also like the Pokemon ones... ;)
