Excellent choice ... The Tale of the Piranha Brothers was one of my favourites. "He nailed your head to the floor?" ... "At first yeah."
"Yeah but he was very reasonable about it. I mean; one Sunday when my parents were coming round for tea, I asked him if he'd mind very much not nailing my head to the floor that week and he agreed, and just screwed my pelvis to a cake-stand."
I used to watch Do Not Adjust Your Set and At Last the 1984 Show on ITV which starred most of the Pythons - I also regularly listened to I'm Sorry I'll Read That Again on BBC Radio with John Cleese (and the Goodies). I remember seeing Monty Python listed in the Radio Times and was hooked.
