A man walked into a bar one afternoon, sat down, and ordered a drink.

After a few minutes, he looked at the bartender and said, “I’ll bet you fifty dollars I can bite my right eye.”

The bartender laughed. “There’s no way. Nobody can bite their own eye.”

The man smiled, reached up, popped out his glass eye, put it between his teeth, and gently bit it.

The bartender stared in disbelief, then angrily handed him fifty dollars.

The man finished his drink and left.

About half an hour later, he came back, sat at the bar again, and said, “I’ll bet you another fifty dollars I can bite my left eye.”

This time, the bartender narrowed her eyes.

“Hold on,” she said. “I just saw you walk in here. You’re not blind, so both your eyes can’t be fake.”

The man shrugged. “So, do we have a bet?”

The bartender thought about it for a moment. It seemed impossible.

“Fine,” she said. “Fifty dollars.”

The man grinned, reached into his mouth, pulled out his false teeth, lifted them up, and used them to bite his left eye.

The bartender groaned and handed over the money.
