Eeyore's the best. He just keeps going, no matter what bad things happened to him that day. I recall stories where he got bounced into a river (I'm looking at you Tigger), lost his tail, had his house stolen, and for his birthday he got a popped balloon and an empty pot of honey. Yet he takes it all in stride.
Here is a short video of Eeyore quotes. I think I've heard most of these at a poker table.

That settles it. I'm wearing my Eeyore shirt the next time I play poker. Other players will see it and associate me with a donkey. Meanwhile, I will play my best, and attempt to accept bad beats with the class and patience of Eeyore.
