I thought the whole statement was done rather "tongue in cheek" as I think that Jonas was a bit surprised that they had a whole section of his interview on it. I found it amazing that when watching the live feed all the housemates with the exception of Ivana and Stephanie were farting. From the H/L's you would have thought he was the only one doing it. Jonas was so badly edited on the H/L shows in comparison with others.
Maybe he was too much competition to their chosen one Alex
