1. Mug a drug dealer. They always have loads of cash on them and what are they going to do call the police? Also I really do not see the moral objection especially if the person is peddling hard addictive drugs.
2. Steal a tank. Enough said.
3. Get in a bar brawl with three to five drunk people that I started. Unfortunately the tenents of wus fu forbid me.
Really, who wouldn't want to do any of these things but most of us have some limits and common sense to stop ourselves and a healthy respect for the law.
