It's a proud moment for any father when he gets to present for a scan of his unborn child. 

But did Jimmy Kimmel really think that this monumental life milestone would go by without Matt Damon having an input?

In the latest installment of the duo's long running "feud", it turns out Damon could be the father of Molly McNearny's unborn child. Of course the only way to settle it is for the trio to appear on an episode of "Maury", titled "The Unbourn Identity" and needless to say there were some surprises for all involved.
