The Colbert Report's Final Episode | Video
Stephen Colbert Ends The Colbert Report With as Many Stars as Possible
It's the end of an era. Stephen Colbert officially retired his ultraconservative character from The Colbert Report on Thursday night — and he did it with quite a few celebrity pals. While many fans speculated that Stephen would "kill" himself off (the show's main guest was Grimmy, aka the grim reaper), it turned out he instead decided to ride out into the night sky. But he made sure to give a treat to the show's famous pals before riding off, leading celebrities and politicians into an epic sing-along. Watch Stephen's celebrity-filled number above, and check out his official sign-off below. And, if you're already missing Stephen, don't worry — he'll be taking over David Letterman's Late Show in late Summer 2015.
