Get a tin can - you can find one in most recycling bins if you don't have one laying around - get some dirty clothes, find a busy street corner, look sad and homeless.
Can bring in a good $15-$20/hour x 10 hours a day x 30 days/month
Upside: No work, get some fresh air
Downside: Long hours, a little bit of harassment, no paid vacations (unless you bring tin can with you)
