Listen, let's not give Piers Morgan — a British TV presenter who's dabbled in racist tropes and transphobia — a gold star. But even he has realized Rudy Giuliani seems a little off.

Giuliani, the former NYC mayor and current personal lawyer for President Donald Trump, appeared on Thursday on ITV's Good Morning Britain,which Morgan co-hosts. The appearance, which took place in the middle of the night in the U.S., turned into a shouting match between two old white guys about who was more discredited.

The fight began when Morgan criticized Trump's tweet about "when the looting starts the shooting starts" in regards to the protests surrounding the police killing of George Floyd. But the argument soon devolved into a barrage of personal attacks.

"You sound completely barking mad, do you know that?" Morgan said.

Giuliani fired back, "No, I don't. You sound like a big liar."

But Morgan kept going after the former mayor, firing off wonderfully British insults.

"You've lost the plot. And it's sad to see," the host said.

Taking a page from his boss's playbook, Giuliani stumbled through a few insults about Morgan's failed CNN show and its poor ratings. At some point, Giuliani either tells Morgan he "sucked up" or "fucked up" — it's tough to tell because Giuliani's words are a bit slurred — but either way Morgan apologizes for the language before twisting the knife further into his guest.

"When I used to interview you, you were an intelligent, reasonable man and you've gone completely mad," he said. "And you sound deranged. You're abusive. And it's really sad to see what's happened to you."

A viral clip from the interview goes on in a similar fashion for a few more minutes. It does represent a shift from Morgan — a former winner on Celebrity Apprenticewho had a largely friendly (if bonkers) interview with Trump this time last year.

But definitely watch the entire clip from Thursday, if only to see co-host Susanna Reid deliver an absolutely perfect, "OK," to end the wild segment.
