A man returns home a day early from a business trip.  It's after midnight.  While enroute home, he asks the cabby, "If he would be a witness..??"

The man suspects his wife is having an affair, and he wants to catch her in the act.  For $100, the cabby agrees.

Quietly arriving home, the husband and cabby tip-toe into the bedroom.  The husband switches on the lights, yanks the blanket back and, there is his wife in bed with another man..!!

The husband puts a gun to the naked man's head.

The wife shouts, "Don't do it..!!  I lied when I told you I inherited money.
HE paid for the Corvette I gave you.
HE paid for our new cabin cruiser.
HE paid for your Packer 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 from side-to-side, the husband lowers the gun.  He looks over at the cabby and says, 'What would you do..??

The cabby replies, "I'd cover his ass with that blanket, before he catches a cold."
