The last few weeks, I participated in the Tweakers.net Microsoft SQL Challenge 2008: a combined initiative between the Dutch Tweakers.net community and Microsoft.
Quick facts
There were a total of 440+ contestants who tried to answer one in depth question correctly every day regarding SQL Server 2008. Everyday, for two weeks in a row. Besides answering correctly, time was an important factor as the fastest right answer would get more points.
My personal result after these two weeks – I came in 15th.

Final note: a big congrats to my direct colleague Ron de Wit for coming in 7th!
