Who was that Jerk?

Today, I don't know why, but I rembered some of the stories that John "Maddog" Hall shared when he was in Ecuador.

John Maddog was talking on a table with a group guys about "Unix" in general. A "Guy" came late to the table to join the discussion. The person of the group that was talking to John gets up and leave the room.  At that moment the "Guy" that came late asked:

Guy: Who was that Jerk? he talked like he invented Unix or something?
Maddog: That guy was Ken Thompson.

Leasson Learned: Always ask the names of who is sited in your table before calling them a Jerk
