Cartoon Cross-overs

Do you like cartoons? Personally, I love them.  I always prefer to watch an animated movie over a real one and some of my favorite cartoons include spongebob and phineas & ferb.  I came across these cartoon crossovers, where artists take two separate cartoons and mash them together to create a completely different cartoon.  My favorite is Dexter's; I used to be in love with Dexter's Laboratory.
