Recently, an old undergrad professor of mine was a speaker on a panel at my law school. I attended the panel's presentation and when question and answer time came I raised my hand.
"Prof. (blank), You taught me business law at (my undergrad) in 2000. You're a big part of the reason I went to law school." I said.
The professor beamed at the idea of having shaped a young life until I followed up with, "Yeah, well, I think you owe me seventy five grand."
Everyone laughed.
Except me.
