Stephen Colbert's soon-to-end Late Show aired an interview with another big-name guest on Tuesday—and Barack Obama used it to needle the current occupant of the Oval Office without ever saying his name. In an interview taped last month at his new presidential center in Chicago, Obama joked that Colbert might not be such an outlandish presidential candidate anymore. "I'm looking for a new gig soon, and a lot of people tell me I should run for president," Colbert said, per Rolling Stone, adding that he thinks it's a "stupid idea." "The bar has changed," Obama said, adding that the host could "perform significantly better than some folks that we've seen," before quickly denying it was an endorsement.
