"How come, every time we get an Inter-Library Loan request for a mucky book I always have to tell them that we can't find our last copy?"
Apparently, somebody's lost the last copy of "The Anne Summers Book of Amazing Sex." I am astonished that we had one in the first place.
"It was bought by accident."
"How does anybody buy 'The Anne Summers Book of Amazing Sex' by accident?"
"God knows. Anyway, it went into stock for the Housebound Library [the old dears in particular like a bit of filth] but then a customer at Umpty put a res. on it and never brought it back. Half of bloody Yorkshire thinks we've got hundreds of dirty books that the staff keep for themselves."
