Marcus destroyed part of the Diary Room and swore at Big Brother yesterday (26.07.09).

The hairy housemate's worryingly erratic, sulky behaviour led him to lose three tokens which he had just won for the house in a Big Brother ‘Mathematical Sense or Mathematical Nonsense' quiz.

The housemates were gathered around a screen in the kitchen and watched as Marcus was introduced to the quiz.

Big Brother told him: "Housemates do not seem to understand the concept of percentages. All too often housemates make outlandish statements which make no mathematical sense whatsoever.

"This troubles Big Brother."

The Wolverine look-a-like was then given examples from conversations between housemates and asked to decide if their statements made mathematical sense or nonsense.

After incorrectly guessing Freddie (Halfwit) saying he was "95 per cent certain" how to make hummus, he correctly guessed his own statement that he was "a million billion percent" sure he would have an "awesome photo" making him "look like a complete top boy" was nonsense.

As Big Brother then announced to the grumpy looking housemate he had passed the challenge and won three tokens - redeemable for a host of goods and hot water for the house - he proceeded to knock over the quiz stand and said "here's some rock n roll for you."

He was told his behaviour meant he would forfeit the tokens, to which he replied with a torrent of swearwords at Big Brother. This led to him being told he would face further punishment later for his disrespect.
