James Fidget (real name) had a false roof to his mouth that clipped on in some arcane way. It didn't clean itself very well, so in between his roast dinner and his custard-drenched pudding he would remove the plastic thingummy and clean it manually. The trick here was to distract him in increasingly surreal ways so he forgot to replace it, and then - when he had eaten a fair whack of the custard - make him laugh hysterically. You haven't lived until you've seen custard flood out of a schoolboy's nose.
