The Colbert Report and the Late Show had a crossover this week.
Stephen Colbert said on The Colbert Report he needed to use the bathroom but couldn’t find the key. He said Letterman must still have it, so he rushed on across to the Ed Sullivan Theatre during a Late Show taping and found it.
Katie Couric also made a guest appearance.
The gag was used primarily to promote donations to the Red Cross for the recent natural disasters in the US.
