Serious question, but warning: hobby-horse/

Just tuned in to Gardeners' Question Time to see if I can stand it.
(I can't.) Am I just a grumpy old sod, or is it still subject to its
old vice of moronic giggling at things which just aren't funny? Why
do they do it? Do they think gardeners are dimmer-witted than other
Radio 4 listeners? Is the next chairman going to be Ainsley Harriott?
