In the Prince song, Sign 'O' The Times, during the part where he sings 'At home there are seventeen-year-old boys
And their idea of fun', I was concvinced he was actually saying, 'At home there are 17 or so boys, and they are all deformed'
Also, in the Janet Jackson song 'Escapade', listening to it when i was perhaps 6 or 7 and was completely oblivious to the existance of such a word, I would happily sing along 'Nes-Ca-Fe, we'll have a good time, Nes-Ca-Fe, leave your worries behind'
