GraphJam is sort of like LOLcats for excel charts. Probably the best use of Excel charts I’ve ever seen. In fact, I wish more Power Point presentations had graphs along these lines! It’s a poignant way to get across a nuanced idea. In fact, it makes me wonder if having numbers in any sort of non-scientific graph is a good idea.
My favorite so far is Good/Bad Idea Chart #16: Bank Heist
