While the ballsweat-palm ranks well below the stinkpalm on the list of disgusting ways to shake another person's hand, it's still pretty gross.
I mean, Lewis Hamilton had just finished qualifying today for the Japanese Grand Prix, and we figure the tight, hot quarters of an F1 car can leave a man's stones just a bit mossy. So when Hamilton groped himself before earnestly shaking rival Sebastian Vettel's hand, we recoiled a bit. Then we laughed, because screw that guy.
