He jumps up in a panic wondering what he's going to say to his wife. He tells the secretary to quickly take his shoes out into the yard and rub them around in the grass. Then he finishes dressing and goes home.

When the man opens the door to the house, his wife is standing in the doorway fuming and asks him where the hell he's been until 8:30 in the evening?
