1. A old school scam used by bums to get money by using a can of dog food and a can of cornbeef and hash. The can of dog food is emptied and cleaned out and the cornbeef is placed in the dogfood can. The bum then sits outside a grocery store eating from the dogfood can and is given money by strangers that think the poor bum is eating dogfood.
2. Any scam where a bum lowers himself to a unethical level, such as pretending to have no legs.
