Macho Man bit by a cobra.

Randy "Macho Man" Savage VS Jake "The Snake" Roberts
At Summerslam 1991, Macho Man and Miss Elizabeth were to be married but while the reception was taking place, they were presented with a present from Jake "The Snake" Roberts: a king cobra snake.
A few weeks after his gift, Roberts attacked Savage in the middle of the ring and tied his arms in the ropes. With Savage subdued, Roberts opened his infamous bag and out came the same king cobra. Roberts held back WWE security with the snake and then proceeded to irritate the snake by slapping it, causing it to bite Macho Man's bicep!
It was at this point things went horribly wrong. Of course, everything before this moment was suppose to happen, including the bite. What wasn't suppose to happen was the snake biting and chewing and Macho Man's muscle tissue as Roberts tried desperately to pull the snake off. With Robert's pulling at the snake, its teeth dug deeper and deeper into the Macho Man before it finally let go.
Luckily (and obviously) the cobra had been defanged so Savage suffered no snake-bite poisoning or major damage to his arm. Due to the gore and violent reality of the angle, it is one of the most original, well-known, and disturbing wrestling angles in the history of the business.
Due to fan pressure, Savage would be "re-instated" as a wrestler by WWF president Jack Tunney so that he could do battle with Roberts. The feud was brutal. During the Tuesday in Texas pay-per-view, Roberts — after losing to Savage — beat him down, then forced Elizabeth to beg for mercy; when Roberts was dissatisfied with her, he slapped her hard across the face.
