Tony Blair is sitting in a barber shop having a haircut, when in walks David Cameron who sits in the next chair. They studiously ignore each other whilst having haircuts and shaves, Tony is finished first and his barber asks if he would like some after-shave applied, he throws his hands up in horror and sez "oh no way, Cherie will say I smell like a brothel"
Dave's barber asks him if he would like after-shave, "yes sez Dave as much as you like, Samantha wouldn't know what a brothel smells like"
