A businessman was having an affair with his young secretary. Every Friday the two would leave work a few hours early and have sex at the secretary's house. When the executive returned home, he would tell his wife he had gone to a bar with his friends.

One night, the executive accidentally fell asleep at his secretary's house. When he woke up, he rushed to get dressed and told his secretary to rub his shoes in the grass. Eager to help, the confused secretary took his shoes outside, rubbed them in the grass, and handed them off.

By the time he arrived home, the executive's wife was waiting for him. She immediately asked him where he had been.

"I am not going to lie to you," he said, "I am having an affair."

His wife slowly looked him up and down, paused for a moment and said, "BS, you've been playing golf!" WHAMMO!
