Ed and Nina Otto really loved their dog Lancelot, and when he died of cancer last year, they decided to spend more than $150,000 to get Lancelot cloned. The Florida couple -- who, by the way, have nine other dogs -- sent Lancelot's DNA to a lab in Korea and made Lancelot Encore. What?

It may seem completely crazy, but, says Ed Otto, "He was a very special dog to us, and we've given a lot more money to the humane society than we've ever spent on this project."

Sentimental and sweet or totally batcrackers? You decide.
