Go play in traffic, seriously.
Mugging people...
Wait for someone about to take out cash from an ATM. If they're wearing a gold watch, they'll almost certainly take out more than $100 at a time.
Once they've taken the money out, bash them over the head with a sock full of loose change.
Take the money, their wallet, and run like the cops are chasing you... because they are.
Profit!
I like the response from another member in a previous douche bag thread like this...
Go to Home Depot
Buy a table saw
Turn it on and get a Carl Lewis running start and slide head first, Pete Rose style, across the blade.
