One day, a man was having an affair with his secretary in her house. Feeling tired, they fell asleep and awoke at around 8 p.m.
As the man threw on his clothes, he told the woman to take his shoes outside and rub them through the grass and dirt. Confused, she nonetheless complied and he slipped into his shoes and drove home.
“Where have you been?” demanded his wife when he entered the house.
“Darling,” replied the man, “I can’t lie to you. I’ve been having an affair with my secretary. I fell asleep in her bed and didn’t wake up until eight o’clock.”
The wife glanced down at his shoes and said, “You liar! You’ve been playing golf!”
