she's the only one on its quite late at night and she says to the driver,
'I know I'm a nun but I've been to the doctors today and he's told me I've only got a week to live. I would like to have sex before I die. The only thing is it has to be with a man who is single and it must be anal sex so that I remain a virgin.'
The bus driver thinks about it and sees she's a nun,
'OK then'
Afterwards the bus driver says,
'I've got a confession to make - I'm not single I'm a married man with 3 children'.
The nun says,
'That's OK I've got a confession to make too, my names Eric and I work at the fancy dress shop.'
