Stephen Colbert is admittedly a bit rusty at in-person hosting. The 57-year-old host of welcomed his first in-person guest, John Krasinski, on Thursday night and the appearance was full of laughs and gaffes. From the moment Krasinski appeared in the recently constructed replica of Colbert's office at the Ed Sullivan Theater in New York City, things were hilarious and awkward. Colbert's wife, Evie, sat by Krasinski's side and the trio couldn't stop cracking up.
