Head Lice The Truth

This story was told to me by one of the Mums at my kids school. I have no reason to think it's not all true.
	Said Mum has a son, who doesn't like having his hair cut. But one Saturday she dragged the lad into a hair salon, plonked him down and the hairdresser set about her work. She parted his hair, and lo, there were head lice everywhere. Off they went to the local chemist, the Mum mortified, even though, as I understand it, there's no actual need to feel ashamed about this common occurrence.
Anyway, she nervously approached the assistant, and in a low voice said "excuse me, but you have anything for head lice?" The girl turned and started rummaging under the counter. After some time she stood, turned and shouted across the shop to a colleague, with a Polish accident: "I'm sorry, but I cannot find any prescription here for a Mrs Headlice, where should I be looking?" Apparently the rest of the people in the shop cracked up on hearing this, and the deeply embarrassed Mum was soon laughing along with the rest of them. Classic.
