What's that you say — looks digitally doctored? I don't know. The basketball never leaves the frame, it takes the right looking bounce (considering how flat it is), and their reaction appears genuine, especially if you guess this took 50 or so attempts to successfully pull off like I do.

But hey, if you're still not convinced, Debbie Doubter, there's a second reverse-angle shot from the field.
