Dumbest home game rule ever?

[Slow Play Ray]

Okay, so we all know some uninformed people play by some pretty dumb rules, but have you ever heard one this bad? My buddy played at his neighbor's house this weekend, and there were a lot of asinine rules he told me, but this was the worst: when it gets to heads-up, they play 6 hands, and the person with the most chips after 6 hands wins. So basically if you have a big enough stack, you can just fold 6 times and win.
