Conan O’Brien’s Long Lost Son [VIDEO]

Could Conan O'Brien have a long lost son?  By the looks of the guy in the photo, it's entirely possible!

This is Greg Keating, he looks a lot like Conan and even has some of the same mannerisms.  Greg posted this video on Youtube, and it's not clear whether it's a joke or if he is seriously Conan's son.

Greg jokes about going fishing and even "dominating late night television" together.  I don't know....it's pretty believable!  What do you think?
