Are you sure on that? I read somewhere that hilariousandco said that he paid 1 BTC to theymos for the title, but I don't know if that was sarcasm or genuine. (Also, I think it was for the Gold Member title)

And I don't think donators can have custom titles. I referred here for that: https://bitcointalk.org/index.php?topic=38071.msg467464#msg467464
