Big Brother's Halfwit had a very "hippie" birthday but said he found it "weird" to celebrate it in front of the nation. Halfwit, who changed his name from plain Freddie after becoming a housemate, turned 24 on Sunday, the day of the summer solstice, so the contestants donned hippie outfits to turn on, tune in and drop out. Halfwit was delighted with his tie-dye outfit but later told Angel: "This is probably the weirdest birthday because it's all being broadcast." He was told to prepare a 15-minute presentation about himself entitled The Life, Times and Thoughts of Halfwit the First, for the other housemates. "I was born with a brain with very little understanding of social signals," he began, adding: "If I had been aware of social signals, it would have crushed me. I've always been a bit different. I didn't notice people calling me stupid." Before entering the house the Oxford graduate, from Market Drayton, Shropshire, described himself as an entrepreneur and polymath. The presentation continued: "I'm a man of many different sides, many different angles. "I sing. I do politics. I am a very social person. I'm a very clever person, but I've had to work really hard to even be able to read and write. "I'm really into politics, but I've been so frustrated with so much of politics." Meanwhile, Ladbrokes has backed Halfwit 5/2, from 11/4, to win the show. And the aspiring politician leads Charlie (6/1) and Noirin (7/1) in the betting. Ladbrokes spokesman, Nick Weinberg, said: "This is the first sustained gamble of the series. Freddie has established himself as the man to beat."
