This tip was sent in from a source in NYC:
A car picked up Stephen Colbert outside his studio tonight and brought him to Conan's taping, and then Conan showed up at Colbert. I guess they are doing their own strike solidarity thing on tonight's shows.All of the late night hosts have been steadfast in their support of not just their own writers but also the hundreds of employees who were affected by the strike. A Conan/Colbert couch swap (man, that sounds dirty) promises some must-see nonsense. We can't wait.
