A man had been sitting at the bar for hours, drinking one beer after another and getting louder with every round.

At some point, he casually mentioned that his girlfriend was waiting for him outside in the car.

The bartender frowned. It was freezing cold outside, and the man was in no condition to notice much of anything.

Concerned, the bartender stepped out to check on her.

When he reached the car and looked through the window, he froze.

Inside, the man’s girlfriend was kissing his buddy Dave.

The bartender shook his head, walked back inside, and leaned over the bar.

“Listen,” he said carefully, “I think you should probably go check on your girlfriend.”

The drunk man blinked, nodded, and staggered toward the door.

A minute later, he came back into the bar laughing so hard he could barely stand.

The bartender stared at him. “What on earth is so funny?”

The drunk wiped his eyes and said:

“That stupid Dave… he’s so drunk, he thinks he’s me!”
