Viewers might consider Rachel Maddow and Tucker Carlson as the stars of their respective networks, but they once shared airtime on MSNBC. The show, which debuted in 2005, was done in a debate-style format which persisted until the duo was split and Carlson joined Fox News. While it's not clear whether Maddow watches Carlson's show, The New York Times reports he definitely watches hers, and when his show goes off air, Carlson often goes to his office where he catches the beginning of The Rachel Maddow Show.

The two may not share the same political views, but Maddow says she bumped into Carlson very early into President Donald Trump's term and as she put it, "It turned out we had both thrown our backs out within one week of each other, with neither of us having ever had a back problem ever before in our entire lives," she said. "I had the gift of a very human-to-human, eye-contact moment with him, like: 'We're both doing this thing that's killing us, and killing us at the same pace.'" When Maddow and Carlson were described as parallel versions of each other, Maddow's response was to laugh and say, "Exactly."
