Young soccer fan meets Pope

There's this young boy from London who is going to the Vatican with his family, hoping to see the Pope. The boy is a bit worried about whether or not they will see the Pope amongst the thousands of people. So his mum says "Don't worry, son, the Pope is a big soccer fan and I know he barracks for Chelsea, so wear your Chelsea shirt, the Pope will see the famous blue and he will stop and talk to you.
The next day, the boy wears his Chelsea shirt whilst they are standing in the crowd as the Pope goes along in his Popemobile. Next thing the Popemobile stops a little further down the street, Pope Benedict gets out to talk to a different little boy, who is wearing a Manchester United shirt. Then he gets back into the Popemobile and it drives right past the young Chelsea fan, who is very upset and starts crying. "Don't worry" says his mum, "The Pope is driving around tomorrow as well, so I'll buy you a Manchseter United shirt, we'll come back tomorrow and then he is guaranteed to stop and talk to you."
So they are back in the crowd the next day the little boy is now wearing the Manchester United shirt. The Popemobile comes along and the boy is all excited. As his mum predicted, the Popemobile does stop, right in front of him. Then Pope Benedict gets out, walks over to the little boy, bends down to talk to him and says "I thought I told you to GET LOST yesterday!"
