Me personally, I would do four things:

1. Go crazy and get every pair or Jordans ever made

2. I would buy season tickets for Notre Dame, Redskins, and the Pacers and work my way on getting ownership in the teams somehow.

3. I would buy any and every Harley Davidson I saw (I dont ride, never have, but I fell in love with these bikes at a young age. Still have all my replicas that I put together and painted)

4. I would get a house similar to the one the founder of Papa Johns has in Kentucky:
