You can play some cracking games during lectures though:
1). When girls come into the lecture room, guess how many penises each one of them has taken in the past week. Always fun to have a guess.
2). When the guv'nor says "We'll take a quick break here", see how many cigars you can smoke outside before feeling sick, or, see how long you make one last. Nothing better than a bit of smoke up the lung.
3). 'Coffee cup knock off'. You know those tarts that always take in coffee and always leave the cup behind? Sit at the back, and throw sweets at the cups to see who can knock the most off. Fills time when everyone is rushing to get through the doors at the end.
4). The old 'can you pick up my pen, please' gag. To punish the infidels that keep dropping their pens on the row in front, kick the pen further down. The next time somebody asks me to pick up their pen, it's getting introduced up their jacksy.
