"You wouldn't understand, there's a bit of male excitement about buses."
This is from Boris Johnson, waxing ecstatic (as he usually does about most things) about London's new bus to replace its much-loved old Routemasters: http://www.guardian.co.uk/politics/2011/may/27/boris-johnson-and-the-routemaster (http://www.guardian.co.uk/politics/2011/may/27/boris-johnson-and-the-routemaster)
So this proves that buses are a male thing? Sorry, Teresa!
