It's probably safe to say Tuesday night's Democratic presidential primary debate isn't going to be as big of a draw as the Republican one: Most people have a tough time naming three out of the five candidates on stage, and there's no Donald Trump.

So CNN is doing its best to keep things exciting: It set up a podium in case Vice President Biden wants to enter the race at the last minute and hop on stage. CNN's Jim Acosta imagined on air what that would look like.

Unfortunately for Acosta, Stephen Colbert caught that clip. Colbert took a cue from his Daily Show days and spent the rest of the segment above mercilessly making fun of it.

Will Biden run for president? Perhaps we'll find out Tuesday night — or if you're CNN, just let your imagination run wild.
