The IRS decides to audit Grandpa, and summons him to the IRS office. The IRS auditor was not surprised when Grandpa showed up with his attorney.
The auditor said, “Well, sir, you have an extravagant lifestyle and no full-time employment, which you explain by saying that you win money gambling. I’m not sure the IRS finds that believable.”
“I’m a great gambler, and I can prove it,” says Grandpa. “How about a demonstration?”
The auditor thinks for a moment and says, “OK. Go ahead.”
Grandpa says, “I’ll bet you a thousand dollars that I can bite my own eye.”
The auditor thinks a moment and says, “It’s a bet.”
Grandpa removes his glass eye and bites it. The auditor’s jaw drops.
Grandpa says, “Now, I’ll bet you two thousand dollars that I can bite my other eye.”
The auditor can tell Grandpa isn’t blind, so he takes the bet.
Grandpa removes his dentures and bites his good eye. The stunned auditor now realizes he has wagered and lost three grand, with Grandpa’s attorney as a witness. He starts to get nervous.
