Great story: last year at the hall of fame tip off at Mohegan, we told my buddy to start heckling Greenberg as he was sitting on press row. He started yelling "Greenberg bubble!!" At him. When Seth got up to tinkle my buddy goes "hey, ask Greenberg how he likes the bubble!" He didn't realize he was telling seth himself this. He thought Greenberg was the guy sitting next to the real Greenberg. Seth flipped him off and told him to have another drink.
So, to answer your question, both my buddy and Greenberg are idiots.
