"More hairspray Bill tighter tie!" he tweeted Friday.
Hader returned to his old stomping grounds to spoof the potty-mouthed Mooch, who sold his company, missed the birth of his child and soiled his reputation to hold the title of White House communications director for only 10 days.
"I heard you two nutless, liberal asswipes mentioned my name, and when I hear my name mentioned three times, I appear like a goombah Beetlejuice," Hader said, impersonating Scaramucci during a FaceTime call.
Hader-as-Mooch maintained that the infamous phone call he had with a reporter from The New Yorker was supposed to be off the record.
"But I guess people didn't like when I said that, and let me see if I can clear this up for primetime," Hader-as-Mooch said. "I said Steve Bannon was trying to S his own C. By the way, I was completely misquoted. I didn't say that Bannon tried to S his own C, he did it. He made contact, tongue to tip!"
"You know how you miss me," he added, "I'm like human cocaine. You got a little bump of me, I made you feel excited, but I was out of your system too quick. And now that I'm gone, you're all depressed and edgy and you're trying to figure out how to score some more of Scara-mooch!"
In case you live under a rock, Scaramucci was fired on July 31 after only 10 days on the job following an obscene phone call he had with a reporter from The New Yorker, in which he flung some extremely explicit insults toward Chief Strategist Bannon and former Chief of Staff Reince Priebus.
Let's relive some of Scaramucci's most shocking statements, shall we?
"Reince is a f-cking paranoid schizophrenic, a paranoiac," Scaramucci said. He channeled Priebus as he spoke: "'Oh, Bill Shine is coming in. Let me leak the f-cking thing and see if I can c-ckblock these people the way I c-ck-blocked Scaramucci for six months.'"
"I'm not Steve Bannon, I'm not trying to suck my own c-ck," he said, speaking of President Donald Trump's chief strategist. "I'm not trying to build my own brand off the f-cking strength of the President. I'm here to serve the country."
"What I want to do is I want to f-cking kill all the leakers and I want to get the President’s agenda on track so we can succeed for the American people."
