Feeding Frenzy: Lemurs go bananas for trousers.
Bristol Zoo's primate keeper, Sarah Monday, aged 21 and from Birmingham, donned a pair of custom-designed banana covered trousers to encourage others to take part in Wrong Trousers Day.
More than 100,000 people across the south west have already signed up to go wild to support Bristol Children's Hospital by swapping their usual legwear for a pair of outrageous trousers.
People are being asked to donate pounds 1 to support the hospital or to sponsor bosses or teachers to wear something wacky on July 6.
Wrong Trousers Day is also taking place around the country to support seven children's hospitals and hospices based in Cardiff, Leicester, Manchester, Newcastle, Nottingham, Sheffield and Stockton-on-Tees.
Bristol Zoo spokeswoman Heather Holve said: 'The zoo is so popular amongst children that we really wanted to be able to help those who are sick or ill by supporting fundraising for the Children's Hospital.'
Sarah, who has worked at the zoo for three-and-a-half years, said: 'The lemurs are incredibly strong, so they were quite close to pulling the bananas off.
