We have all heard about internet videos that go viral, but this is simply a picture. Oma Katie works for Arizona State University, just like Jenn and Tony, and she was asked to pose for a picture on ASU's HR page. You can see the picture there, you'll have to wait as the photos scroll through. I've copied it and pasted it below.
They told Katie she could bring any "ASU" stuff for the photo shoot, and so she picked Thomas!
