David Ross, Mr. T get set for DWTS season premiere
"My character gonna come out, my 'A-Team' gonna come out," Mr. T said. "I say I pity the other competition, they dared me, them fools ain't got a chance."

"I have not seen my costume, but I've heard it's gonna be a little tight and got some bling on it," he said. "I think there's gonna be a lot of different colors this season I'm not used to wearing, but I'm comfortable in my own skin. I'm excited about it all."

"I already have blisters, and my feet feel like they're on fire," she said. "So it's very different 'cause we're dancing in heels. And for 13 years, I've been running around the gym like I'm Tarzan barefoot, so very different."

"Sasha is the very first boy I've ever danced with!" she laughed.
