Night Out in London (S02E04)

Will convinces the guys to transform into fashionable club-goers, so they hit the road to London in Simon's car. However, to get into the hottest nightclub, Simon has to trade his stylish trainers for a pair of disgusting old shoes belonging to a homeless man. Meanwhile, Neil accidentally injures himself while urinating into a can, and when Jay checks out the situation, they're thrown out for being perverts. Just when they think it can't get any worse, they discover that Simon's car has been wheel-clamped.
