Entrepreneurs Mark Cuban, Arianna Huffington, and Shane Smith were among the throng of celebrities joining a sing-along to help send off Stephen Colbert in his final episode of The Colbert Report.

The tune, a rendition of Ross Parke and Hughie Charles's "We'll Meet Again," was of course led by Colbert, joined by his former boss and fellow TV show host Jon Stewart. Also in the tribute chorus were Willie Nelson, Gloria Steinem, Bill Cranston, Katie Couric, James Franco, George Lucas, and Cyndi Lauper.

The skit was just one in the farewell show of the news satire, which aired Thursday on Comedy Central and featured a string of surreal and star-studded scenes, where the self-aggrandizing character even went so far as to murder the Grim Reaper and achieve immortality. Oh, the power of funny TV.

The entrepreneurs' presence was fitting for the ending of the show, which often blurred the lines between skewering and celebrating American capitalism and U.S. values, all while guests had fun not taking themselves seriously. Cuban, Huffington, and Smith have all previously appeared on The Colbert Report's hot seat, along with such other famous entrepreneurs as Richard Branson and Bill Gates.

Although this satirical character may be saying farewell to the cameras, Colbert himself will return next year, but on CBS, where he will be David Letterman's successor on The Late Show.

The episode concluded--after a bizarre skit revolving Santa Claus, Abraham Lincoln with a unicorn horn, and Jeopardy host Alex Trebek--with a behind-the-scenes blooper take of Colbert and Stewart, in which the hosts both finally addressed their characters. When Stewart asked him what he was doing, Colbert gave the most succinct way of describing his widely adored yet egocentric character: "Getting angry at liberals," he said.

After the episode aired, political, and sports commentator Keith Olbermann tweeted that Cuban had finalized his deal to bring NBA player Rajon Rondo from the Boston Celtics to his team, the Dallas Mavericks.

Leave it to Cuban to not take any time off, even when filming the farewell episode of a popular TV show.
