A man, his wife, and his buddy are at a bar.
After a few hours of heavy drinking, the wife says she has had enough and she is going out to sleep it off in the car.
Ten minutes or so later the buddy says he is going out to check on her.
Several beers later, the bartender suggests that the husband go check on them both.
The husband stumbles out the door and sees his buddy and wife engaged in a few extracurricular dealings, then walks back in.
He laughs and tells the bartender, "That buddy of mine is so drunk, he thinks he is me!"
