Rafa is one of the stars taking part in a publicity campaign for the "Special Olympics" which will be held in Barcelona, Vilanova and Geltru from 11th to 14th October.
The clip above shows Rafa's participation under the theme, "Sport makes us equal, special". The event is being held to commemorate the 20th anniversary of Barcelona hosting the Games back in 1992 and of the first Special Olympics.
I don't know if Rafa will be making any sort of appearance but he's obviously happy to lend his name to the campaign itself.
