This is an old clip, harkening back to the hilarious failure of Ben Carson to get on stage during the Republican debate just before the New Hampshire primary. If you missed it, here is what actually happened at the debate. It never gets old for me.
And here is Stephen Colbert making his entrance on his show.
That wasn’t Ben Carson’s failure nor Trump’s nor whoever those others are…
that was a spectacular failure on the part of the stage managers.
However, the Colbert bit is hilarious.
