All right, I should have tested it before my comment. I took napa's word for it. (Though that's the first time I've ever seen an 8 ball variation coded that way) I see all for of %r = 6 will be triggered at the same time, not just the first one. Still, though, that's not a wise approach, and it simulates spamming. I wouldn't go that route if I were the author of this snippet.
Gummo, I recall you saying that before. Deja vu :P
