30 Rock Season 3 Episode 22

Jack's on the hunt to find his birth dad. Only problem is there are three to choose from. When Jack is introduced to them one by one, it makes for hilarious scenes. When Jack's figures out which one he is, the man says he's so happy to meet him. Jack starts warming to the idea that it's because the man wants to be a 'real dad' to him. The reason is much funnier.
