It starts out sweetly enough -- with a selfie taken in what looks like a foxhole decked out with a wading pool -- before everything turns quite literally icy. To welcome Lindsay Lohan to what was actually her second visit to the new 'Tonight Show' (remember she showed up on that first night, along with the rest of Hollywood?), Jimmy Fallon engaged the starlet in a game of Water War.

The rules are simple enough: players turn over a playing card, and whoever's card has the higher value gets to splash their opponent with a glass of ice cold water. Sure, it's Fallon's game, but Lohan ends up being really, really good at it.
