According to
Webster's Revised Unabridged Dictionary, a pict is "a race of people of uncertain origin, who inhabited Scotland in early times."
Why does this matter? Oh, I'll tell you why this matters. If you were paying attention while listening to the great Pink Floyd album Ummagumma, you'd have noticed that the word pict was used in the song title Several Species of Small Furry Animals Gathered Together in a Cave and Grooving with a Pict. Yes, a Pict. I reckon that Roger Waters was referring to the strange Scottish rambling during the end of this song. Were these words actually spoken by a person of uncertain origin? Yet another Pink Floyd Mystery...
