A married man was having an affair with his secretary. One day, their passions overcame them and they took off for her house, where they made passionate love all afternoon. Exhausted from the sex, they fell asleep, awakening 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. Mystified, she nonetheless complied. He slipped into his shoes and drove home.
"Where have you been?" demanded his wife when he entered the house.
"Darling, I can't lie to you. I've been having an affair with my secretary. We were having sex all afternoon and I fell asleep."
The wife glanced down at his shoes and said, "You're lying! You've been playing golf!"
