The housemates were set a task where they had to roller-skate around the other bedroom whenever Big Brother ordered them.
They were given three minutes to get ready and if they weren't on their wheels within that time it would count as a no-show. Three no-shows and they fail the task. The only time they would never be told to skate was after 1:00 am.
They all went to bed one night at 11:00 pm. Big Brother then told them twice to roller-skate. Tim didn't show up for either of these because he had already taken out his contact lenses.
He then went to the diary room to ask Big Brother if the two no-shows would count and proceeded to get quite angry when told they would. He animatedly proclaimed something like, 'You are clearly discriminating against people who wear contact lenses! Comprende!' It was really quite funny. The general consensus is that he made a bit of an idiot of himself.
I'd choose either this incident or Alex's nominations as the best diary room moment.
However, as far as I'm concerned, the Jade's birthday diary room moment could go in the awkward moments poll. I cringed when I saw it. When they showed it on BBLB the mental scars were reopened.
