Lost in translation?

(Our new official BMCC Library poster)

Last week a colleague sent me this joke in an email:

A bloke walks into a Glasgow library and says to the prim librarian,
'Excuse me Miss, dey ye hiv ony books on suicide?'
To which she stops doing her tasks,
looks at him over the top of her glasses and says,
'F**k off, ye'll no bring it back!'

I'd seen it several times before so read it, smirked (again) and deleted it.

Said colleague has just been in to my office to ask me what the joke was about. They said they'd been trying to work it out for days.

Was it the Scots she was having trouble with and I was the only one able to translate? No. It was the rudeness of the librarian's answer! That was inexplicable - not like a Blue Mountains City Library staff member at all!!!!!
