In Germany, am 17. Mai geboren is a euphemism for 'homosexual', because the relevant provisions of the Penal Code were contained in Art. 175. The story is told, in one of Upton Sinclair's novels, of an art exhibition during the Nazi years at which the number was allocated to a painting of young men on the march entitled 'Spirit of National Socialism'. Unfortunately, the fact was pointed out at a preview by an American journalist; the director was shot, and the number reallocated to a still-life of a vase of flowers.
