Unfaithful?

[Rondy]

A man, returning home a day early from a business trip, got into a taxi at the airport. It was after midnight. While en route to his home, he asked the cabby if he would come in with him and be a witness.
Suspecting his wife was having an affair, he intended to catch her in the act. For £100, the cabby agreed.
Quietly, the husband and the cabby tiptoed into the bedroom. The husband switched on the lights, yanked the blanket back and there was his wife in bed with another man. The husband put a gun to the naked man's head.
The wife shouted, "Don't do it! This man has been very generous! I lied when I told you I inherited money. He paid for the BMW I bought for you. He paid for our new Rolex. He paid for your Everton season tickets. He paid for our house at the lake. He paid for our country club membership and he even pays the monthly dues!"
Shaking his head the husband slowly lowered the gun. He looked over at the cab driver and said, "What would you do?"
The cabby said, "I'd cover him up with that blanket before he catches a cold."
