When Stephen Colbert and Jimmy Fallon cross-pollinated their shows by promising to be Best Friends For Six Months, someone forgot to do the math. Fallon showed up on The Colbert Report last night, and they discovered that the calendar says they’re not friends anymore - but not before they worked in a Harry Potter reenactment and a reference to their competing at the Emmys on Sunday.
By the end of this clip they’ve sworn to be Enemies For Six Months, and another surprise guest, with his own new show to plug, offers himself as Fallon’s BF replacement. Take a look.
