A British woman has married a dolphin. The touching ceremony took place at Dolphin Reef in the Israeli port of Eilat (which is, I guess, where the dolphin lives). The dolphin is named Cindy, but despite the female name seems to be a male. (That would have made it even more unconventional if it was a gay interspecies marriage.) No word on where the couple plan to honeymoon. And one can only speculate on whether this marriage will ever be consummated.
This may be the first human/dolphin marriage, but I don't think it's the first interspecies marriage. After all, I've posted before about Marry Your Pet, the website that provides a marriage certificate to those who want to wed their beloved animal. As for weird weddings, the other example that comes to mind (besides Lisa Marie Presley and Michael Jackson) is that woman who married a dead poet.
