If I eat the cold pizza
in the fridge, that's an ass factor of 2 (ass leaves couch, get pizza, ass touches seat), whereas going to
Burger King is an ass factor of 4 (ass leaves couch, touches car seat, leaves car seat and then touches couch).
If I get up and get a beer, that's an ass fact or of 2. If
you get it for me, that's an ass factor of 0.
