Top Banana

I once worked with someone who used to sing Harry Belafonte's Day-O song constantly, like a CD on repeat. I'm not sure whether they'd watched Beetlejuice too much, or if it was some actual psychiatric condition that prompted them to sing incessantly about bananas, but as I recall, the novelty wore thin quite quickly.

Still, I knew another person outside of work who did more or less the same thing with the theme from Chitty Chitty Bang Bang; and in a contest to see which can drive me to a homicidal rage more swiftly, the six-foot, seven-foot, eight-foot bunch doesn't even get a look-in.
