Mr. Mime.
Not going to post a picture because I don't respect it enough to save a picture long enough to post it.
Who designed that stupid thing? It's ugly, it's anything but cute (despite trying desperately to be such), the proportions are freaky. I don't like it, I don't understand people who do.
Ash's mom is crazy for keeping one of those little psychopaths around, it needs to be burned alive. Sure, it's good for helping around the house, but you know what else is good for that? Machoke. Machamp. A Gardevoir or Gallade would probably be willing to help out. Heck, most humanoid pokemon would, and some would even be aesthetically pleasing.
But no. It just HAS to be one of those hideous little things.
You want to know a freaky thought?
Wild Mr. Mimes. They're out there, little pedophile beasts that are perfectly willing to rape your children, then entrap them in invisible boxes that it made. At least Hypno probably like eats it or something instead.
Bastards probably have a good idea on how to use human tools, too. You could be lost in a forest, and in the distance, see a camp fire. Are you saved? No. They're Mr. Mimes, and they're eating and raping children while keeping the spares in an invisible box, letting them watch and cry. They see you. You're surrounded. You're in a box. You're next.
Fucking Mr. Mimes.
