From his bestie Josh, to the experts - who were dry-retching - it was grim.
EXPERT MEL: 'Oh, woah.'
EXPERT JOHN: 'C'mon.'
EXPERT TRISH: 'That is a terrible thing to do. So childish.'
MEL: 'It’s so aggressive.'
Hayley then told Steve of Mishel, 'Your wife was the first to tell me, so I didn’t use my toothbrush.'
MEL: 'Oh she didn’t use it.'
TRISH: 'Thank God.'
JOHN: 'That’s really crossing a boundary. Using a toothbrush for that.'
MEL: 'It’s vulgar.'
STEVE: 'The toothbrush is not cool. Not cool.'
MICHAEL: 'I don’t think anyone deserves that, as much as I despise Hayley.'
MEL: 'That is disgusting. That could make her very sick.'
CONNIE: 'Her health could have been so damaged.'
Things escalated when Hayley pulled out the said toothbrush.
'She’s got the toothbrush, she’s got the toothbrush,' Trish gasped!
'Every dog has their day,' Hayley said to producers, smirking.
Then, Hayley really brought the house down, and possibly fecal matter.
She threw THE toothbrush across the table, over castmembers, to her husband. It JUST missed his face.
Hayley was an emotional wreck.
Mishel begged the truckie, 'Dave can you just apologise to her for f—k’s sake?'
But David showed no remorse, saying, 'I’ve been nothing but a gentleman throughout this experiment.'
