Roy Bird was a fat, ugly smelly kid in our year, who defied all convention by not being treated with disgust. In fact, we was almost popular.
It was considered to be an honour if you were chosen to be Roy Bird's special helper. At dinner time, he would randomly select an individual from the group clamoured around him, by method of getting another group member to spin around, eyes closed and point to a person.
The winner got to accompany Roy in tasks such as aggravating the school retard, and collecting cigarette nubs from behind the 6th form block.
(Out of interest, Google Roy Bird, and you get... gasp! It's Fred West! A bit.)
