Well one clearly couldn't fall asleep sitting behind brother 'hoagie' gumby but I'd love to know the mechanics of how one falls asleep at a convention. How do you stop your head falling in your lap? It sounds like a real skill and could even spawn a new industry in seat enhancers to hold you upright.
I mean, s urely this brother's gonna wake up with a crook neck?:
PS: My mother sleeps at assemblies and snores quite loudly I'm told.
