Indeed, I have been using them jokingly in the knowledge one day I'll have to swallow my dignity and start speaking like an arse myself.
The day I become a fat, middle-management company man who's always walking around with beads of sweat on my balding head, sucking up and saying things like 'I want to see a little bit more happy out of you. Think of us as your family and every day is Christmas', maybe then I'll start speaking like an arse. For the moment I'm happy to talk like a normal person. It still gets to message across.
