Well of course I recognised it as a fake, but I was amused that this went viral and quite a few quite respectable blogs carried this video of JPII pracicing his baseball skills before a Mass somewhere in a US baseball stadium, they have now mostly been taken down.
The clues are obvious, white shoes - not red, or the reddish brown worn by JPII, Signor Gamerrelli would never produce a cassock and fascia like that.
As for the habits of the assistants, what order are they?
The informality and lack of defference too seem quite out of place.
Who can spot any other signs?
