EI,
Yes I would. I would sit quietly at the bar and let Mo ramble to his hearts content. Every so often, I would ask a question or make a lengthy comment that he would further be unable to get out of, and he would only dig himself in deeper.
Once he was deep enough into his own trap, I would ask that question outloud to him just as I did on this board. While the record screetched to a stop, someone would drop a beer glass, and the room would fall silent. All eyes would be on Mo, and he would stutter, then avoid the question and start rambling again. The real big guy sitting at the other end of the bar (the African American football player) who silently listened to all of this, would stand up and say....."hey bro, why don't you answer the question?"
I would then sit and watch the fun.
