Based on this stupid story from the US.
Imagine it, go to mass, wake up in time for the Eucharist, go up and get your piece of cardboard.
The Pope give you the cardboard and says "Ze body ov Khrist" (Fine I don't know what the stereotypical German accent is because I don't notice it).
You pretend to put it into your mouth, and start to walk away.
The next minute in front of something like 50 000 rather devout Catholic youths:
"I'VE GOT HIM!!!! I'VE KIDNAPPED YOUR PRECIOUS MESSIAH!! YOU CAN HAVE HIM BACK FOR THIRTY PIECES OF SILVER!"
Ideally 50 000 Catholics should see this as a joke and not beat you to death.
