Johnny Knoxville has 20 doctors' phone numbers in his mobile phone.
Knoxville 42 performs dangerous stunts on each episode of reality series 'Jackass' - has suffered so many injuries throughout his career, but still says he doesn't "give a shit" about getting hurt because he is used to it.
But as a precaution Knoxville says "I've got 20 doctors' numbers in my phone! Recently, I fractured my elbow and right now I have a torn shoulder.
He goes on to add, "My left side's my impact side so it's all f***ed. And my back's blown out but I don't know what else to do besides move forward. It's what I do and a big part of it, so I don't really think about it.
Just as an after thought the crazy actor adds "And I have asthma! But I don't give a shit - I'm fine with it."
The stuntman doesn't worry about getting hit after provoking someone during one of his pranks either, being far more concerned about fans suing him if they punch him and hurt themselves.
He recently told Nuts magazine: "I don't give a shit about being punched, but I don't want someone to hit me wrong and then their knuckle hurts, so they sue us.
"In America there are lots of lawsuit, so when I'm trying to get someone angry I'll bring 'em back down. Then I'll get 'em angry again, and bring 'em down."
