One time in class, a professor asked one of those "raise your hand if you've heard of ______" questions that are commonly asked before diving into a new topic. As always, some students raised their hands half-way, hesitant in their own recollection. What came next was likely a lifetime of waiting for the perfect opportunity. Hell, maybe the professor became a professor for the sole purpose of having the opportunity to make this joke. He said, in the exact words that I will never forget: "Okay. I see some hands and I see some Parkinson's."
And that was the best moment of my college career.
