Engage in jobjacking

Buy an Exxonmobil shirt on the internet, and stand at the local filling station. When people stop for gas,talk to them! For example, "The money from your gas today is going towards helping us defeat the indigenous people of Alaska and exterminate the violent polar bear of the Far North. Thank you!"

Or, for example, become a Wal-Mart greeter. Introduce shoppers to some really weird products....
