Agolfery!
Eric was having an affair with his secretary at work. Overcome by passion one day they took the afternoon off and went to the secretary's house where they made mad passionate love all afternoon. Wracked with exhaustion, they fell asleep naked on her bed and didn't wake up till 7.30pm.
Quick said Eric, get dressed and take my shoes to the front garden, then rub them all over the grass and in the mud. The secretary didn't know why, but she did as Eric asked. Eric got dressed and put the shoes on.
When he got home, his wife wanted an explanation as to why he was so late home.
Eric said, I can't lie to you sweetheart, I have been having an affair with my secretary and we fell asleep on her bed till 7.30pm.
His wife looked at his shoes and said, Liar, you've been playing golf.
