|1.||Rules of the road|
Whenever you are doing someone a favour and giving them a ride in your vehicle there are 3 options for payment for this favour:
2. Grass (i.e marijuana)
3. Ass (e.g. sex)
Joe "Hey dude, can I get a lift after hockey?"
Mark "No problem, cash, grass, or ass though - sorry bro, rules of the road"
Mary "Can I get a ride home after work?"
Bill "Sure you can; cash, grass, or ass?"
