I'm surprised there hasn't been an update to this here in this thread, but in the latest issue of "Magic" magazine Wayne explains his side of what happened.
It seems the host, Franklin Barazarte, who is not normally the host of that show (he is the Producer and Director and his wife is usually the host) seemed to have planned this as he was not even paying attention to Wayne and his team during the interview; as if he was preoccupied. Then, as they were saying their goodbyes on air, the host asked to "bless" Wayne, and after having a bottle of "Spirit Water" (Agua de Florida, a flammable cologne) poured and lit in his hands, dumped it and then spread it all over Wayne's head! The host's excuse was that he was trying to cleanse Wayne of evil spirits!
The article is worth a read to get Wayne's side of the events, and it doesn't really make me yearn to perform magic in extremely superstitious countries such as the Dominican Republic...
