Late for work, John was getting berated by his boss.

“What’s your excuse for being an hour late?”, the boss questioned.

John began, “I started off on time, but the roads were so slippery, that for every step I took, I slid two steps back.”

His boss wasn’t convinced, “Really? Then how did you manage to get in to work?”

“I finally gave up and decided to turn back and walk home”, came the prompt reply.
