Kimbo Slice: “I wasn’t a professional MMA fighter. Before I was a street thug.”

More proof that Kimbo Slice is taking the sport seriously:

“The main thing I’ve learned is there’s a big difference between street fighting and this,” Slice said. “When I was a street fighter, I’d wake up and have a fight and I’m done. Now there’s more preparation. The guys I’m fighting are professionals. I wasn’t a professional MMA fighter. Before I was a street thug.”
