I rate Farrah Abraham as one, Makosi as another, Grace Adams Short, and Kinga bottlegate.

Four nutters in different ways but each one kept you watching, even if it was from behind a cushion in Kingas case.

Shahbaz is the ultimate.

The two most annoying nutjobs have been Marco and, er, Marco

To be an outright nutter would suggest a level of mental instability. Shahbaz is the only housemate that truly falls into that category (and possibly Sree).

Not the most obvious of nutjobs but Steven The Significant is up there solely for his complete and utter delusion!

oh Dear God, yesss...(.*vomit smiley, sorely missed)

Imagine an ultimate BB with the following

Alexandra
Shazbaz
Helen
Charley
Hughie
Saillie
Dennis
Steel
Fight night emma
Bb6 lesley
Kenneth tong
Wolfy

Granted not all nut jobs, be interesting to see who would win though
