Yeah, I shot a 16 last night. Aced everything, then my shot on #8 landed in the basket long enough for it to count, and then spun up out of control and went into #9 basket, the same thing happened on #14-#15, sort of an off night. 
This reminds me of doc's quest for a legitimate circle 2. We have discussed it many times and it seemed that it was simply impossible, until, we came up with a penalty stroke at USM that allows for it. On hole #1/#10 there is a statue in play that if hit costs you a penalty stroke but you play it where it lies. So, hit the statue and carom into the basket and there you have it, a "Circle 2". Andy Jewett nearly did it just a couple of weeks ago and ended up with a drop-in circle 3.
But I'm not going for Jack's description of a negative one stroke by making two baskets in one throw. Sounds more like that would be an ace followed by a black ace that means you owe me the five bucks I just paid you for the ace you just got....
