That said, I used to work at a place where this one manager could not stand the song Copacabana by Barry Manilow and he made the mistake of mentioning that it would get stuck in his head and drive him crazy. Needless to say, being the sympathetic guys that we were

, we'd occasionally text him with "Her name was Lola..." right as he was walking into a meeting. A couple of times there was a pause then we could hear "Arrrrrgh!!!" coming from the conference room!
