All the lads were sitting in the smoking room...
This was in a factory I used to work in, back in the days when it was socially acceptable to sit inside and smoke. It was the mid morning tea break and was heaving when in walks Dave. He's just had a haircut which Rob who was sitting on the chair happened to notice. Now it should be noted that Rob had the most god awful teeth known to man. Crooked, smoke stained yellow protrusions that made him look like he'd had his teeth replaced with rotten bits of corn. So typical working class English teeth in every way.

So as Dave sits down Rob took it upon himself to comment on his new haircut loud enough so the whole room could hear, "Oi, Dave. I hope you didn't pay the cunt who did that to your hair".

Quick as a flash Dave shot back, "Yeah, well at least my hair will grow back. Your teeth fucking won't".
