The point of this thread is a serious one though. I have done half a dozen or so childrens' discos in the past and I always find it almost impossible to keep the boys entertained. Girls are easy, they know all the music, all the dances (which I eagerly try to copy) and are really willing to join in.
Boys can be a nightmare. Peter Kay hit the nail on the head in his live act, where he describes how the little swines are only interested in running the length of the dancefloor and sliding onto their knees (I would add, smashing into as many dancing girls, and DJs, as possible).
How do you cope with this? How do you keep the little sods from creating mayhem?
