I bowled a 666 once and didn't bowl another 600 for about 4-5 weeks (this was about 3-4 years ago)
Didn't have another chance at one until this year... had 656 going into the fill ball in the 10th... we had already won the game so I tossed it in the ditch on purpose. I don't care how bad you throw a ball, you can always luck up and get a strike.. I wasn't chancing it again.
