For charismatic party guy Jack Fuller (Ashton Kutcher) and buttoned-up commodities trader Joy McNally (Cameron Diaz), a rowdy weekend coincidentally shared in Las Vegas should have, by all rights, ended up being little more than a random blur. That is, if these two vacationing New Yorkers didn't have a signed marriage license staring them in the face to shockingly remind them of the giant misstep they took while feeling no pain, Vegas-style.

Stacking the deck, not only did Jack and Joy tie the knot after tying one on, but later scored a mind-blowing three million bucks in a slot machine bonanza. Well, Jack won it with Joy's quarter. At the machine she'd already been playing. Or was it the other way around? And whose loot is it anyway?
