Who would that be? Drew Barrymore and Tom Green? Lisa Marie Presley and Nicholas Cage? Julia Roberts and Lyle Lovett? Robin Givens and Mike Tyson?

Who could forget Carmen Electra and Dennis Rodman? The Baywatch babe and the rainbow-haired basketball star tied the knot in 1999 to cap off a night of heavy drinking in Las Vegas. Rodman sought an annulment 10 days later, claiming he didn't even remember the ceremony.
