The Welsh visitors had fought back from 20-6 down at half-time to take the lead thanks to Dan Parks' boot and tries from Bradley Davies and Richie Rees.
Shane Williams gifted Francois Trinh-Duc a try in the same match, fly-half Stephen Jones gave one away in the loss to England, while during the autumn internationals Dan Biggar committed the same sin against Samoa, while Jonathan Davies' kicking howler against Argentina was every bit as bad.
