Rachael Lilenthal's right arm was bitten off by a monster alligator last August, and she lived to tell the tale. It happened while she was swimming in a picturesque river near Orlando - just 50 miles from the Disney World resort where a 2-year-old boy was snatched by a gator Tuesday night. "I was not aware that it was an alligator at first but sure enough, when it clamped my arm, it's a big ole' gator's head sitting right there. It was most definitely an alligator on my arm," she told Inside Edition.
