Mishapalooza 
After GDC, a friend of mine decided to throw a party. In true Misha style, though, this wasn't a house party with 50 people.
It was Mishapalooza, a massive warehouse party with 600 people at its peak. It featured open bar, two dance floors, professional music and lights, a karaoke room, and...drum roll...jello wrestling! Oh, and some really great people. It was an incredible amount of fun.
