Two men were hunting in the woods. One was a fanatic who hunted as often as possible. His friend was hunting for the first time. He didn't want to hurt anything. After a couple hours, they saw deer tracks. They soon caught up with the deer. The deer was slow because it had a terrible infection in one eye. The eye was swollen closed. The hunter lifted his gun to shoot the deer. But his friend begged him to stop. "Can't you see ...

... that's a bad eye deer?"

Yeah, that's a pun all right!
