We used to wind up a small but violent first year called James Lloyd Wooller using a similar method. We would start in the morning by groaning "Woooooooooooller" when he entered the common room for morning assembly. Even the prefects and some of the younger housemasters would join in. If, or rather when, he responded in anger, he would be met with mock-stern shouts of "James!" or "Lloyd!", which would set him off even more.

This ritual humiliation probably made more of an impression on us than it did on him - Wooller only lasted a year before being expelled, but me and many of my old schoolfriends (now well into our mid-20s) continue to respond to any expression of anger or irritation with "OK, don't go James" or "That's fucking Lloyd". Even my mum still says it.
