I Bite Sign

This is a sign for your parrot cage to let everyone know not to stick their fingers in there. They're going to do it anyway because the bird is so pretty and the bird is going to bite them and they're going to bleed everywhere while screaming "IT BIT ME! THAT BIRD BIT ME! OMG I'M BLEEDING!".

But you can rest easy... because you put a sign on the cage clearly telling them they would be bitten by the bird.
