Spelled "N-E-R-D"

So, shlepping in to work today, I start humming "I'll know" from Guys and Dolls. Nothing particularly unusual about that, but when I get to the "Chemistry? Yeah, chemistry" part, I suddenly segue into Tom Lehrer's "Elements" .

If I ever do a cabaret show (and make enough money to pay people to come), I'm gonna haveta remember that combination...
