7KFC advertised an event at which local rap group Fama would pull a bus at one of its stores. Time to put in a bit of muscle then, because your average single-decker weighs 7? tonnes. But there was no bus outside the venue in Cameron Road, Tsim Sha Tsui. When we went inside, two of the rap group's members, Cheng Sze-kwan , aka MC C-Kwan (left) and Luk Wing-kun, aka MC SixWing, (far left) - surrounded by fans - were pulling a model bus with a piece of string along a table. Other games included how many times you could switch a lamp on and off in a minute. And if that wasn't enough gut-tickling, fab fun for one day, the boys (pictured) were promoting the fast food chain's new 'Chewy Cheeze'. The duo were wearing items from the clothing line of their boss, actor Edison Chen Koon-hei. Earlier, singer Juno Mak Chun-lung said his and his brother's fashion label had been around for about 10 years branching out to markets in London, Paris and Japan, whereas Chen's clothing line was more like a bunch of friends making clothes just for interest's sake. 'We are in a very different market. His is more street fashion and ours, Silly Thing, is more about high fashion.' The rap group agreed. There was nothing to compare because 'street fashion is a style, not something to judge based on how valuable the clothes really are', Luk said. Cheng added: 'Maybe ours is more street wear. I see a lot of people wearing our brand on the street.'
