The craziest pin motion I've ever seen was a high pocket 6-10 where the 6 slid almost all the way over to the 7 pin spot. Scorer saw a 7-10 split, and the bowler converted the split.
I still give her flack for that, because I don't feel it was a true 7-10 split since the 6 (7) pin was forward and to the right of the 7 pin spot.
