Jon Stewart And Stephen Colbert Crash 'Conan' In NYC (VIDEO)

Conan ended his week in New York on a high note Thursday by officiating longtime costume designer Scott Cronick's wedding on the air, but it turns out that regular Conan fans weren't the only people who wanted to witness TV history.

Jon Stewart and Stephen Colbert were both hidden within the theater and trying to blend in with the audience members while Conan gave his monologue. The only problem? Conan spotted them.

It's crazy to see how many audience members whip out their cell phones when they realize they're sitting near the "Daily Show" and "Colbert Report" stars, but between the wedding, the surprise cameos, and scheduled guest Louis C.K., we can't blame them.
