I was an undergrad working at a bookstore when Bo's Michigan Memories came out, and he did a signing. The signing was scheduled for 4:00. He was the consummate professional. Bo walked in the door at exactly 4:00. He asked the name of everyone who came up to him, looked them in the eye and shook their hand. He stayed until everyone who wanted an autograph got it (which meant staying about an hour beyond the scheduled time), and he put care into that signature - every letter of the name "Bo Schembechler" was legible, as was all the dedications. He double-checked to make sure he was getting people's names right before he put pen to paper. It was clear that in his mind, when he made a public commitment, he was truly committed to being at his best, even if it was just a routine book signing.
P.S. OP - it's Fritz Crisler, not Chrysler.
