An old man is lying on his death bed with his wife at his side. They had 3 kids but the last one, Steve, looked nothing like the first 2 so he was always suspicious. The old man looked at his wife and says: "Hunny, it doesn't matter at this point but I need to know. Is Steve my son?" His wife smiles and says: "I swear to you, he is your son". The old man then dies peacefully. Then his wife says: "thank god he didn't ask about the first 2".
