Bob Newhart mentions SMU with Craig Ferguson

This is totally random - was watching Craig Ferguson last night and he had Bob Newhart on - they were chatting about his popular sitcoms from back in the day and they started talking about a drinking game called "Hi, Bob" - then Bob said "I heard it started at the Southern Methodist University, I hope it did - I mean, they liked the show, it was a compliment to the show" - the conversation starts on this Youtube link at about 25:58: https://www.youtube.com/watch?v=_9SXpi7apEo
