Your lectures are indeed something special, many of them you have talked about rather strange things. But they do keep people awake and we do listen. Using things like SEX for sign extension makes it much easier for us to remember them. You could be very right when you say that your lectures seem 10% information, 90% entertainment, the highlight so far has to be the day you shaved your head and coloured it blue for charity (just like the Intel chaps) never thought I would see you do something to remind us of Intel, maybe next year you could dress up similar to bill gates and let people cream you?
