A man walks into a bar with a giraffe. They both order a round of drinks and start chatting with the bartender. The bartender says, "Hey, what's with the giraffe? You can't have that in here."
The man responds, "Oh, don't worry, he's with me. He's my service giraffe. He helps me reach the top shelf at home and he's great at keeping an eye out for danger."
The bartender looks a bit skeptical but decides to let it slide. As the night goes on, the man and the giraffe start getting pretty drunk. The giraffe starts stumbling around, knocking over tables and causing a ruckus. The bartender has had enough and says, "I'm sorry, but you need to leave. And take your drunken giraffe with you!"
The man apologizes profusely and tries to corral the giraffe out of the bar. As they stumble out onto the street, the giraffe looks at the man and says, "Man, I think I'm gonna have a hangover tomorrow."
The man looks at the giraffe and says, "You think you're gonna have a hangover? I have to explain to my wife why I came home drunk with a giraffe!"
