and the harder you try not to laugh the worse it's gonna get.
Dr. S, professor of Greek Mythology, why a math major had to take such classes, was beyond me.. Dr S was a jingler. He'd come into class and start spewing, his left hand in his pocket, jingling his change, all thru the class, non stop, constantly, every day, and by the end of class, he'd look pretty spent (no pun intended)
Speculation was that he was jingling change as a cover to what he was really doing, and that there was a hole in his pocket and he'd make himself "happy" during class.
I'm not sure I've ever recovered from the giggles that I will get when I hear someone jingling their change -- because I'm pretty certain I know what they're doing.
Just go with it... laugh if you must... volunteer to be his dueling partner...
