During a segment on Monday’s Late Show, Colbert pretended to go to a log cabin and knocked on the door of his friend’s retirement home. Out came a bearded Stewart in a bathrobe, who did a spit-take as Colbert informed him Trump would be the GOP nominee.

The two then recalled Trump’s bankruptcy records of the past 30 years.

Colbert’s conservative, megalomaniacal alter-ego, “Stephen Colbert” from his days on The Colbert Report  — armed with a sword and Captain America shield — joined Stewart and the CBS host for the gag.

Stewart retired from his hosting duties on The Daily Show in June 2015, Colbert ended his tenure on The Colbert Report in December 2014. 

On The Late Show, Colbert also resurrected an old segment from his Comedy Central days, “The Word,” where he examined the idea of the word, “Trumpiness” connecting it to “truthiness.”

“Truthiness has to feel true, but Trumpiness doesn’t even have to do that,” Colbert said. “And, if [Trump] doesn’t ever have to mean what he says, that means he can say anything. Here’s the deal, truthiness was from the gut, but Trumpiness clearly comes from much further down the gastro-intestinal tract.”

The convention is proving to be comedy gold for all the late night comics.

Samantha Bee took aim at Trump’s running mate, Mike Pence, on Full Frontal, saying: “Indiana hates Mike Pence as much as Indiana Jones hates snakes.”

Jimmy Kimmel joked about how the convention is “one Dennis Rodman away from a new season of The Apprentice.”

Seth Meyers had his audience in stitches on Late Night, when he said: “Donald Trump's campaign manager, Paul Manafort, told reporters that, ‘once Donald Trump is accepted by the American people as someone who can be president the race will be over with.’ I assume he means the human race.”

Current Daily Show host, Trevor Noah, who will begin broadcasting live from Cleveland Tuesday night, told Inside Edition that the RNC is “totally unpredictable.”

The South African comic hosted a compilation episode Monday night where he gathered clips as to how Trump became the GOP frontrunner.

He told his viewers: “I should have asked if you were ready. I’m from a Third World country. It looks like you are headed for one.”
