My boss came into work one day, with the most godaweful, patchy looking shit on his head that anyone's ever seen.
Being a typical smartarse, I asked him if his wife cut his hair.
Yep, cost me $15 for the clippers, and every next one is free.
Poor bastard only earns $125,000 per year, so needs to be a little frugal.
Koichi, I haven't had a haircut for over two years - I win (no cost, no effort)
