In tonight's Big Brother, housemates must brush their teeth for one minute with an unusual substance.
David is first up and inbetween constant gagging and retching, he successfully manages to brush his pearly whites with Stinking Bishop cheese.
'I shan't be having that on toast,' he resolves afterwards.
Dogface is challenged to scrub her gnashers with pickled catfish but gives up after a short attempt declaring, 'I can't do that'.
Marcus's task involves tofu but the unflappable wolfman completes it with ease.
Lisa and Charlie ask David how many sexual partners he's had. Charlie estimates 'about 100', but David maintains that he will not have sex 'at the back of a skip or in a toilet.'
Dogface predicts she will be up for eviction this week, along with Marcus and Siavash.
To take their mind of nominations, Dogface experiments on Siavash with some wax strips...
See all the action in Big Brother on C4 tonight at 10pm.
