Who are you calling a Chimp, Chump?

I drew this yesterday, while half watching the TV. I was tired and I really remember drawing it. The only bit I recall doing is the charcoal background, because I did that this morning.

Missing Shark.

I think I originally started this before Christmas 2010. I found it this morning, while looking for some cardboard to pack a parcel with. I did eventually use this to that do that. I don't like the tail, though it's alright.
