is that a nun in the background?
…Kinda. It’s Andy Baker, dressed up as a nun.
The back story, and more information on the nun can be found here http://www.chiefdelphi.com/media/photos/33218.
As for the picture, the frame moments before this one had both Andy and Wayne pointing, however it did not have Libby’s priceless face. Sometimes you can’t have the best of both worlds.
You can, with the magic of Photoshop!
