A duck, a deer, a skunk and an elephant are sitting in a bar The end of the night rolls around and the waitress asks who is going to pay the tab. The duck says that he can't pay because he only has one bill. The deer says that she had a buck on her last night, but won't have any doe until spring. The skunk says he can't pay because he only has one scent. Finally, the elephant says ""It's okay boys, the highballs are on me!""
