A heads up from Mysdirection informs me of this wonderful prank performance created by the Improv Everywhere team. Their latest mission was to have a team member act lost at the Yankee stadium during a game. He kept appearing but just couldn’t hear his mates yelling and waving at him. This continued for a while until whole sections where waving and screaming to help Rob get back to his seat. They describe the event and have pics and videos at the mission page. Lots of fun.
