This was posted by SpiderWebcomm in a thread awhile back about Scotty Townsend:
Scotty learned how to play position well by playing in his fathers tavern. The tavern was swamp-side, and may flies would begin to land and congregate on the table during the hotter summer days. If you swatted them away, they'd just land again and keep congregating. He figured out that if he went into the swamp and caught a bull frog and put it on the table, the frog would start tonguing-up the may flies so he wouldn't have to keep swatting them away. Wherever the frog went, he just played around the frog. If the frog was sitting on his tangent line, he'd twist the cue ball around the frog to get to where he needed to go. After a long time doing this, his frog-avoiding-accuracy was super-high, which translated over time to accurate position play.
