Is this Conan O'Brien's long lost illegitimate son? Let's examine the facts.

Greg Keating's mom worked at 30 Rock in the early nineties. She was promptly fired after getting pregnant. And Keating looks an awful lot like Conan O'Brien.

Case closed.

Regardless of whether or not Conan owns up to abandoning Keating, I have to agree with YouTuber A Just Cause: "Conan will see this and im 100% it will be on the show."
