Clemens also came to Norway do the .NET Extravaganza on April 9th last year, the day Germany invaded Norway in 1940... [Andreas Eide's Weblog]

I did 5 (!) sessions in a row at that event, with 700 people listening. That was a trip.

In contrast to 1940, the German left after just one day, though, and didn't cause any major damage except to his own health.
