This is a breezy little tune about not being able to break up with a really annoying person. It doesn't come from my or anyone else's reality. I mean, who doesn't know that rabies is a serious disease? Who's that stupid? Still the conceit is enough to give the tune a fairly exasperating end for the hapless narrator.
In the semi-interesting facts department, did you know that all instruments except the drums are fake? Obviously, the backing singers and the claps are also real, but yes, everything you hear - bass, harpsichord, guitar, koto, chinese zither, etc. - are all virtual instruments.
