A Cubs fan involved in a verbal altercation with New Jersey governor Chris Christie at a baseball game on Sunday is now challenging Christie to an MMA fight.

(He’s mostly joking.)

Earlier this week Brad Joseph wrote a Facebook post about the incident with Christie, apologizing for saying “you suck”. “So Chris, if you’re reading this, I’m sorry. I didn’t have much time to think of anything to say, and I wanted to express my displeasure with you. I could have done better than ‘you suck,'” he wrote.

He added he didn’t apologize for calling him a hypocrite.

Christie didn’t seem to read the post and told CNN on Monday that he confronted Joseph because he said “awful stuff” in front of Christie’s kids. “I took it the first time he said it, and yelled it from about 15 yards and said some really lousy, awful stuff. And then I came back after having ignored it the first time, and he went in for seconds,” he said.

So, in an interview with WPIX on Tuesday, Joseph upped the ante and challenged Christie to an MMA-style fight. The amateur mixed martial arts group Tuff-N-Uff, he said, agreed to put on the event. (The Las Vegas-based group did not immediately respond to a request for comment from For The Win on Wednesday morning.)

From WPIX:

“If he wants to get into the ring, I would absolutely be happy to,” Joseph said. “I’m sure he won’t but he seemed interested in provoking a physical conversation. “He really seemed as if he wanted to turn this physical.”

He added later (again, he said he’s joking) that he would spot the Governor one punch.
