Donald Trump welcomed Joe Biden's desire to tussle with him — though the Republican nominee said Tuesday it was in "the back of the barn" to the vice president's "behind the gym."

"Did you see where Biden wants to take me to the back of the barn?" Trump asked supporters at a rally at the Tallahassee Car Museum in Florida. "Me."

"I would love that," Trump said. "Mr. Tough Guy. He's Mr. Tough Guy.

"He's Mr. Tough Guy, when he's standing behind a microphone by himself.

"He wants to bring me to the back of the barn," Trump continued. "Oh. Some things in life, you could really love doing."

Biden expressed his desire in a campaign speech Friday for Hillary Clinton in Wilkes-Barre, Pa., as he slammed Trump for his comments about groping and having sex with married women in a 2005 videotape with "Access Hollywood" co-host Billy Bush.

"The press always asks me, don't I wish I were debating him?" Biden said. "No, I wish we were in high school.

"I could take him behind the gym. That's what I wish."
