McDonalds on the way home

Michael wanted to go to McDonalds on the way home from the gym today. He was in a poopy mood. Sharon told him if he saw a McDonalds on the way home, than we would stop. I whispered that there weren't any McDonalds on the way home, she said she knew. Michael happily got in the car and was looking and looking for a McDonalds all the way home. He eventually got sad he didn't find one. I'm not sure if he knows he was duped, but I thought it was a fun way for Sharon to avert a tantrum.
