(This joke is so old, it's probably already on this thread somewhere. I don't care. I like it, plus it's religious.)
A guy is driving when he hears a disembodied voice say, "Drive to your bank." He ignores it, but a minute later it says, "Drive to your bank, now."
He gets to the bank and the voice says, "Cash out your checking account." He hesitates, slowly gets out of the car, and goes and cashes out his account. Back in the car, the voice says, "Catch the 11 a.m. flight to Vegas." He obeys quickly this time. Five hours later, he's in Vegas. The voice says, "MGM Grand. Now." He gets there, enters, and the voice says, "Roulette table with Antonio." Right in front of him is roulette, and the croupier has a name tag: Antonio. He gets to the table and the voice says, "Straight up bet, everything on 17." He places the bet, the wheel spins and spins, and the ball falls on 6. The voice says, "Fuck."
