By the way, we always sang "flip-flap she flied", not flip flop.

As a very young kid when I was in the "cubs" (the junior version of the boy scouts, to which I never progressed) we used to sing this every year in the "gang show" (sorry, I'm putting all these terms in inverted commas because I don't know if such things exist over in the states) "Flip-flap she flied" was, for some reason, always our favourite verse.
