I remember during BB3, that the housemate's surnames just rolled off the tongue.
Jonny Regan,..Alex Sibley,..Kate lawler,..Jade Goody,...with nearly every one of them, you can remember their surnames with ease.
But this year,...I'm not so famliar with them...The names Jon Tickle and Cameron Stout,..no problem,..but the rest of them...I have to really think about it.
Scott,..err Turner,..Ray..what is it again?..oh yes..Shah.
After that, I really have to start thinking about it. The names are just not as memorable as the BB3 HMs.
Nush,....is it Novak?...As in Kim Novak.
Anouska,..err...Gobbleoffski,..is it??
Tania de Marco,..yes I'm sure I've got that one right.
Gos...Gos.....Gos What???
Shows how much they captured our imagination. From the link that Tamara gives,..it really looks like they just didn't have a clue what Steph's surname was...When in doubt,...just give 'em any old name,..Smith'll do.
Steph Smith
She got to the final, for God's sake,..and hardly anyone outside of this forum really has a clue who she is.

Says it all really. A testament to how much these personalities had an effect on our Summer TV viewing.
