Letter: Comb your teeth!

Sir: So it's all pedantry, is it? Head lice infestation is spreading. Perhaps this is because parents are trying to pick out their children's nits with a device often referred to in radio interviews these days - the "fine tooth-comb". If they used a fine-toothed comb (the sort the Radio Doctor would have recommended), and reserved the tooth-comb for tooth-combing duties only, the head lice problem might be solved.
