A man went out to a bar with his buddies late one night, and he got so drunk he ended up having sex with a girl at the bar. He knew his wife would be livid when she realized what he had done, so before he went home, he rubbed chalk on his hands. He walked through the door at around the crack of dawn, and his wife yelled, "Where have you been?!"

"I went out with my buddies to a bar," he replied, "and I ended up getting laid by this girl at the bar."

"Let me see your hands," she screamed, so he showed her the chalk on his hands. "You damn liar!" she exclaimed, "You went late-night bowling again, didn't you?!"
