Technically, apparently, he was kidding. But with Old Crazy Uncle Joe, who can really be sure?

Biden appeared on “Morning Joe” for a Tuesday interview with co-host Mika Brzezinski and said he would immediately retaliate if Trump started poking fun at his behavior [during the 2020 debate].

“I would say, come on Donald, come on, man. How many push-ups do you want to do here, pal? I mean jokingly,” Biden said.

“I’m used to bullies and so my strategy is, just to go out and remember that famous expression my grandpop used to use … they said to Harry Truman, give them hell Harry. He said no, I’m just going to tell them the truth. They’re going to think it’s hell,” Biden [told Brzeznski].

Who’s ready to see two old dudes engaged in feats of strength and endurance on the 2020 debate stage? With Biden a scrapper from Scranton and Trump a pugilist from Queens, this election could shape up to be something along the lines of “Gangs of New York.”

Bring it.
