Jon Stewart has been off TV for a while now. So, when the former "Daily Show" host took over "The Late Show" Thursday, he had a lot to say. 

Stewart stopped by Stephen Colbert's late night show on Monday and joked about returning to television to cover the Republican National Convention — Colbert went live on CBS each night following the RNC. On Thursday, following Donald Trump's nomination acceptance speech, Stewart made his triumphant return. The comedian weighed in on the 2016 presidential race in a biting rant reminiscent of his old "Daily Show" monologues.

"The Republicans appear to have a very clear plan for America, and they’ve articulated it throughout the convention," Stewart began. "One: jail your political opponent. Two: inject Rudy Giuliani with a speedball and Red Bull enema. And then, three: spend the rest of the time scaring the holy bejeezus out of everybody."

Stewart mocked Trump's convention speech, comparing the candidate to an "angry groundhog," but soon pivoted to his favorite target — Fox News.

"With the Rio Olympics coming up, I’m enjoying the gymnastics portion of the program that’s about to occur," Stewart joked. "That would be the contortions that many conservatives will now have to do to embrace Donald J. Trump, a man who clearly embodies the things that they have, for years, said that they have hated about Barack Obama."

Stewart, wearing an ill-fitting blazer and clip-on tie — he and Colbert joked that he had been off the grid for a while — chastised conservative media pundits for embracing the lack of experience, divisiveness and elitism of Trump that he said they claimed to hate about Obama. Stewart was especially harsh on Fox News host Sean Hannity, whom he referred to as "Lumpy," claiming he forgot his name. The comedian played clip after clip of Hannity previously criticizing Obama for traits that he later praised Trump for having. 

Stewart said there was a greater reason for the apparent hypocrisy. 

"Either Lumpy and his friends are lying about being bothered by thin-skinned, authoritarian, less-than-Christian readers-of-prompter being president. Or they don’t care, as long as it’s their thin-skinned prompter-authoritarian-tyrant-narcissist," Stewart said. "You just want that person to give you your country back. Because you feel that you’re this country’s rightful owners. There’s only one problem with that. This country isn’t yours. You don’t own it. It never was. There is no real America. You don’t own it. You don’t own patriotism. You don’t own Christianity. You sure as hell don’t own respect for the bravery and sacrifice of military, police and firefighters."
