We had two recently: Dudley, which at least ensures he will be the only one in his class, and Nero, which presumably ensures he will be the only one in the country.
Luckily I heard both names third hand so had composed myself by the time I had to make appreciative noises. The worst snort scenario I ever had was a woman in the street shouting "Tiggy!" after her daughter. I thought it was a bit twee but quite sweet till she then shouted "ANTIGONE!" I nearly choked - the poor, poor girl.
