eating contests discust me.
One of the student unions at my old university (for historical reasons there were two; a mainstream sporty one and an alternative subculture one that developed from the men's and women's unions respectively) has an iron stomach contest during fresher's week each year. One of the rounds in the competition used to be to swallow a live goldfish, but it was discontinued on animal welfare grounds and now the competition limits itself to morally defensible acts such as the yard of ale race.
