Still from Charmion:

I have never had the privilege of visiting beautiful downtown Dundern, Saskatchewan, centre of romance and intrigue, fortune and fame; I learned that "Screw-Guns" parody from my brother, who served in the same air-defence battery as Bdr Bailey and Gnr Bulloch. I imagine that, on this exercise, they were playing with -- yes, this is its real name -- the Blowpipe anti-aircraft missile.
