And of course there's an "unofficial" official Tech Ed drinking game:
Every time a demo crashes: take 1 drink.
Every time a demo doesn't crash: take 2 drinks.
TechFest: take 6-10 drinks. Be restrained: you will need to be up early tomorrow to find which first-session speakers are most hung-over and to ask them very complicated and demanding questions VERY LOUDLY. (LATE BREAKING RULES CHANGE: Apparently I'm in the first-session slot the next morning. Therefore, the new rule for TechFest is: either (a) take 6-10 drinks and go to Kirk's session in the morning, or (b) take 20+ drinks and wake up in a bus station outside Otorohanga wearing nothing but your delegate pass, somebody else's socks and a strategically superglued trial DVD of SQL Server 2008.)
Every time a Microsoft speaker says "innovation," "community" or "super excited": take 1 drink. After taking 5 such drinks in a row, shout "Bingo!"
Every time a 200 level presentation includes a demonstration containing the phrase "Hello world": take 1 drink and yell "I told you not to call me 'world'!"
