The Sceptic Tank still occasionally succumbs to nightmares about playground bullies and their penchant for so-called nettle boxer shorts. Nettle flannels (stinging nettles rubbed on your legs) and nettle baths (pushed into a ditch full of nettles) were bad, but nettle boxer shorts were the worst, for obvious reasons. Kids are great, aren't they?
