The special edition of CBS' "The Late Show with Stephen Colbert" broadcast Tuesday night was about a rare TV reunion as host Stephen Colbert invited "The Daily Show" alums. Along with Jon Stewart, former host of "The Daily Show," Colbert welcomed Samantha Bee, John Oliver, Ed Helms and Rob Corddry.

All the guests who were invited to Colbert's show Tuesday night were as popular as him and sharpened their satirical skills by being correspondents on "The Daily Show" before quitting it and starting something of their own. 

The Tuesday night special episode was timed to coincide with Colbert's 20th anniversary in late-night TV. He started hosting the "The Late Show with Stephen Colbert" since September 2015. Before that, he worked for Daily Show from 1998.

While there were impromptu acts by the guests, the show also took on a traditional format in between where Stewart and Colbert talked about Trump's firing of FBI director James Comey. When the crowd started cheering on hearing it, Colbert chided them for doing so, but in a sarcastic manner. Then, Stewart compared the audience's reaction, through his actions, to those people who first learn how to surf and catch a wave and then again fall in a heap.

Then, the duo also talked about the recent firing of former Fox News host Bill O'Reilly. Stewart recalled doing a O'Reilly's show and when he left the building, he admitted, he saw little heads popping out of offices, similar to what it is showed in "Indiana Jones and the Temple of Doom," where the children in the mine plead to be taken out of it.

There was also a part in the show which included recreating a scene from the break room of "The Daily Show" in summer of 2005, the time when Colbert left the show to start a spin-off series, "The Colbert Report." The scene showed Bee entering the room, with a perm and a jacket, and she started lamenting about Colbert's departure from the show. "I can't believe you're leaving right in the middle of the George W. Bush administration. There's never going to be another president this good for comedy," she said.

Then, Corddry and Helms also entered the scene, saying they wanted to know which of them would get Colbert's position after Colbert left the show. Next, Oliver entered to find his yogurt and on opening the refrigerator, he found Stewart hiding in there, eating the yogurt.

The guests also reminisced the days when they were all correspondents for "The Daily Show" and faced hardships while being on assignments.

Colbert's show had become controversial after he criticized Trump last Monday for abruptly walking out of an interview with CBS News’ “Face the Nation” host John Dickerson. 

"Sir, you attract more skinheads than free Rogaine," Colbert said criticizing the president. "You have more people marching against you than cancer. You talk like a sign language gorilla that got hit in the head. In fact, the only thing your mouth is good for is being Vladimir Putin's c--- holster,” he continued, even as the last bit was bleeped out.

Colbert faced backlash for his lewd comments on Trump. However, the viewership of his show, reportedly, increased even after the incident.
