I won $2 when I was a kid and the lady wouldn't let me cash it because I wasn't 19. It was really stupid. But if I won:
I would walk down the streets of Vancouver and strike up conversations with homeless people, and give money to those deserving.
I would bring all you kids to Whistler (my hometown) who want to come, and party harder than we have ever done.
Give Franko (the Whistler Hobo) a new guitar, and buy him a beer.
Buy a ton of explosives and blow up the stupid Peak to Peak Gondola.
Then drop out of college and live my life the way I want. Start my own bakery, and feed anyone who asked.
