Well shiiiit

During a show at the Mirage on Horn's birthday on October 3, 2003, a seven-year-old white tiger named Mantacore attacked Horn. (The name of the tiger has frequently been misspelled as "Montecore" in media reports.[16]) As part of the act, but veering off script, Horn held the microphone to Mantacore's mouth and told him to say "hello" to the audience. Mantacore responded by biting Horn's sleeve. Horn swatted the tiger and barked "release!", while standby trainers unsuccessfully attempted to distract the cat with cubes of meat. Possibly incited by Horn's retreat, the tiger leapt at Horn, swinging at his legs and knocking him off his feet.[16]

As trainers rushed to the stage to assist, Mantacore bit into Horn's neck and dragged him offstage toward his cage. Trainers finally got the tiger to release Horn by spraying him with CO2 fire extinguisher canisters, which was the last resort available.[16]
