Synopsis:
Robin and Ted miss their flight to Chicago and try to trace back the events that led up to it. It all started with a penny that Ted found, which caused him to take Robin to dinner across town. That led to Lily wanting to camp out at a bridal sale, causing Robin to get no sleep and need a nap at Marshall's. Then Marshall stubs his toe and Barney runs a marathon for him to settle a bet. But Barney is tired from the marathon and can't get off the subway so Ted jumps a turn-style to come get him. He then has to go to court for jumping the turn-style which makes him late for his flight.
