The story:

Summer holiday after highschool, on the piss with a few mates, including one who prides himself on his lyrical knowledge. Realised that despite knowing the rest of the lyrics (and the name of the song) I never figured out the obvious. When questioned on what I was singing, I figured I must have the lyrics wrong, but didn't know what I should be singing so I tried to mumble the words. Didn't float and I got the piss taken out of me for the rest of the night.
