Big Brother's Halfwit has said he found celebrating his birthday in front of the nation a "weird" experience. Halfwit, who changed his name from plain Freddie after becoming a housemate, turned 24 on the day of the summer solstice. Big Brother said the solstice was often associated with hippies and gave the housemates some costumes to wear. 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. "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."
