What an anticlimax – Big Brother could have found so many ways to introduce a man into the all-female Big Brother house, but instead a vaguely handsome man got routinely slung in and the whole thing got padded out for 90 bloody minutes.

Think of what Big Brother could have done – the first male housemate could have been desperately ugly or gay or married or a male impersonator or a goat with a painted-on moustache but no – instead we've got Ziggy, possibly the most blandly self-satisfied tit in all of Big Brother history, which is really saying something. How will Ziggy's arrival alter the dynamics of the Big Brother house? You know, unless it involves three gallons of petrol, a length of rope, a flamethrower and those awful shrieking twins, we're not even sure that we care.

But anyway, here's the first part of this week's Big Brother betting odds to win – for Charley, Shabnam, Lesley and Emily – with betting odds from Paddy Power…

Charley – The first rage explosion of Big Brother is always a highly anticipated event, so hats off to Charley for providing us with it. The clues were there from the start, after Charley freaked out about Lesley pissing in the shower when actually it's a well-received fact that everyone pisses in the shower and people who say they don't are liars. Anyway, that wasn't Charley's big Big Brother flare-up, though – that came when she furiously accused everyone of eating her food, charmingly calling them all "fat fucks" in the process. Chances are that, unless something major happens his week, Charley will be put up for Big Brother eviction. And, as the Big Brother housemate who got booed the loudest upon entry, chances are she'll be first out. Current Big Brother betting odds – 66/1

Shabnam – Why is Shabnam such an outsider to win Big Brother at the moment? Imagine yourself trapped in a lift with Shabnam for even two minutes. That's why she's such an outsider. Every waking moment of Shabnam's life inside the Big Brother house is filled with a constant spewed stream of attention-seeking "Ohmigod ohmigod, everyone come here and look at me! I'm so crazy!" babble to such an extent that we're starting to honestly believe that Shabnam would stab a baby to death with the heel of a shoe if the Big Brother producers said it'd get her a nanosecond more airtime. Shabnam has the potential to become the Nikki of Big Brother 2007 – and let's not forget what a ghastly nobhead Nikki was. Current Big Brother betting odds – 40/1

Lesley – There aren't enough old people on Big Brother. After 70-year-old Ken Russell stole the show in Celebrity Big Brother by screaming the word "SERVANTS!" at Jade Goody over and over again until it sent her racist, it's time to see what Lesley can do on regular Big Brother. Although ten years younger than Ken, Lesley has still come to Big Brother with the sort of demented twinkle in her eye that suggests she's slyly out to infuriate everyone. So far, Lesley has had a slash in the shower in full view of others, demanded that Big Brother supply her with a milk jug and just generally stood around intimidatingly on the periphery, not really sure of any Big Brother conventions. Still, at least the sooner Lesley is evicted from Big Brother the sooner we can see her topless in Nuts, right lads? Lads? Lads? Hello? Current Big Brother betting odds – 33/1

Emily – For anyone as crap at names as we are, Emily is the blonde Tory who thinks that she's the world's biggest indie fanatic because she saw a picture of Pete Doherty in The Telegraph once. You know, the one who probably travels around the inside of her castle on the back of a golden pony. So far, as we've been able to tell, Emily hasn't done a single inside the Big Brother house of interest yet, except for annoyingly look like most of the other girls in the Big Brother house. So why is Emily so near the bottom of these Big Brother betting odds? Probably because she's a drama student. Nobody likes drama students. Nobody. Current Big Brother betting odds – 25/1
