Bam Margera has sent a clear message to Johnny Knoxville as he says he wants to knock him out in the boxing ring all in the name of revenge.
Margera 43, and Knoxville, 52, aren't shy when it comes to putting themselves in danger for the good of entertainment, as showcased by their work in the Jackass series.
The two men, among others, have created a name for themselves as daredevils as they put themselves through incredibly painful, yet hilarious trials all to make people laugh.
Unfortunately, things have taken a turn in recent years as Margera's co-stars became concerned for his well-being and they made him sign a waiver that he would attend treatment and remain sober, and in return, he could be in the latest Jackass movie, as per TMZ.
Those who have seen the movie will know that the 43-year-old didn't make an appearance and he has now challenged Knoxville to a bare-knuckle fight in revenge for what he refers to as the "death waiver".
Taking to his Instagram stories, Margera said, via the Daily Mail: "So this is not a brand new idea. Knoxville and Tremaine made me sign this f***ing basically this death waiver to take 18 medications that made me a zombie. I couldn't get my d*** hard, I couldn't f*** my own wife, I couldn't get muscles, bald hair, fat weight gain. F***ing motherf***ers."
Jeff Tremaine is Jackass' co-creator but Margera claimed that he is "too much of a p**** to get in the ring with me."
He continued: "But Knoxville if I double dog dare him, he says if I double dog dare anything he will do it. So Knoxville, I double dog dare you to get in the ring with me without any boxing gloves so I could ring, ring, ring I f*** you up.
"Let's go. P****. Oh if you call him a p**** he really gets mad. P****."
Margera had previously sued the creators of the show after they allegedly fired him for failing a drug test before shooting the latest movie.
Part of the complaint read, via The Hollywood Reporter: "Margera did not slip up. He followed the provisions of the Wellness Agreement to a tee, at great personal cost.
"Defendants' treatment of Margera exacerbated his mental health issues and led to suicidal thoughts. But still, Margera persevered - only to have the rug pulled out from under him."
Late last month, Margera was seen "making a scene" at a restaurant which subsequently resulted in him being arrested for public intoxication.
It is thought that he was arguing with his estranged wife Nikki while in the presence of their five-year-old son Phoenix after Margera became unhappy with how his son is allegedly being kept from him.
Nikki, who has been married to the TV star since 2013, filed for legal separation from Bam in February, citing irreconcilable differences.
Knoxville is yet to respond to Margera's request for a fight, but given how concerned his former co-stars are for his health, it's doubtful that he will accept.
