You all know how that turned out for "Lights Out."
But when Slice stopped by Monday's edition of The MMA Hour, he said he had never been offered a fight against Toney, but was certainly open to the idea.
"I never heard anything about me fighting James Toney, but you know, like I said, again, I'll fight anybody, man. C'mon, everybody knows that about me from my street-fighting days. Put anybody in front of me, train me to be the best, I'll fight the best. That's one thing about Kimbo Slice that everybody knows."
Slice has teamed up with his old MMA promoters, Gary and Jared Shaw, to try his hand at boxing. Jared Shaw recently told MMA Fighting that he hopes to see Slice make his "Sweet Science" debut later this year.
As for Toney's MMA debut, Slice said he was surprised at how poorly Toney performed against Couture.
"Yeah, kinda. I was [surprised]. I would have sprawled out," Slice said while chuckling.
Despite his lackluster MMA debut, Toney still believes he can be a force in the UFC, and there's no question that he would take an opportunity to fight the man he calls "Simba" Slice.
Oh, and if you are wondering if that nickname bothers Slice, it doesn't.
"No, it don't bother me, man. That sh-- don't bother me. I'm a grown man.
"That's how they do it. That's part of the game. They can talk sh-- all they want to, but when we face-to-face, they ain't going to do that. I'm not a sh---talker. Never have been, never will be."
