What's your favorite vanity pet?

What does a vanity pet do for my gameplay? If we're talking about adding to my combat potential, it does absolutely nothing. But if we're talking about providing bragging rights, companionship, amusement value, and another layer of personal customization, such a pet has plenty to offer.

Right now my favorite vanity pet is probably the Super Adventure Box spider mini in Guild Wars 2. Not only does it look totally rad in a 16-bit way, but it occasionally does breakdancing even in the midst of dire peril. Dancing retro spider with sunglasses, that's a win any way I look at it.
