During a tourist show at the Pike National Forest in Colorado, a man was having some trouble with one of the fiestier alligators.  A female handler had just given way to a male handler who has not been named.  A second male handler came over to lend a hand and somehow the first handler got his thumb inside the mouth of the alligator, who promptly bit it off as the handler screamed in pain.
