A man had been drinking at the bar for hours when he mentioned something about
his girlfriend being out in the car. The bartender, concerned because it was so
cold, went to check on her. When he looked inside the car, he saw the man's
friend, Dave, and his girlfriend kissing one another. The bartender shook his
head and walked back inside.

He told the drunk that he thought it might
be a good idea to check on his girlfriend. The fellow staggered outside to the
car, saw his buddy and his girlfriend kissing, then walked back into the bar
laughing.

"What's so funny?" the bartender asked.

"That stupid
Dave!" the fellow chortled, "He's so drunk, he thinks he's me!"
