‘Mind-bending’ photo of giant Bidens and tiny Carters baffles the internet

The Carter Center released a photo showing Joe and Jill Biden during a visit with Jimmy and Rosalyn Carter -- but something seemed askew.

Both couples looked happy enough to spend time together, but the Bidens appeared to be about three times larger than the Carters, most likely due to a wide-angle camera lens -- but the strange effect set off speculation both humorous and serious.
