Most of them are only known because of other reality shows and have no discernible talent or use.
Even the supposed 'celebrity' BB is full of freaks now. Heavy D... What an utter ***. He is a *** in Storage hunters (or whatever the show is called) and is only known for being an annoying *** on there that can't possibly be a thick or *** as he makes out.
Haven't watched it for years - you cant convince me that the "spats and situations" that occur aren't proposed and scripted by the organisers to get more viewers! Surely no normal people would behave in that way! What a load of rubbish!
