I'm on the point of getting my free telly licence then losing it within a few months. There will be many of the best jokes which amused my ancestors. I was probably on the receiving end of the agar jelly humour as recently as the mid 1950s. The real hoot was that agar jelly is a sterile medium. Mixed reception because some of the more perceptive girls thought that shooting blanks, long before the expression was coined for vasectomies, would be a good idea.
