The mobile clinic rolls into the West Midlands for Boys vs Girls. Dr Christian meets Kate, who's worried about having an extra hole above her anus, and Luke who has asymmetrical testicles. Dr Dawn meets 19-year-old Jodie, who's struggling with bad breath from regurgitating in her mouth after meals. Dr Pixie visits at a secondary school to warn against the dangers of smoking and conducts spot tests to see which teen students have been having a crafty fag behind the bike sheds.
