Grumpy Cat
Well, I mean, look at that face. I think it says it all. I guess we can't suspect all grumpy cats to be murders (do their bird offerings count as murder?), but I don't think we should assume that cats are innocent, either. Lets take the middle ground and say that we like looking at cat memes, but we wouldn't give them our house keys.
Grumpy Cat will live in our hearts forever.
