Two young nuns decided to sneak out of the convent on a Saturday
night. They went into town and had a whale of a time.

Unfortunately when they got back to the convent slightly the worse for
wear in the early hours of the morning they found the gates locked. There
was nothing for it but to try to scale the high wall by scrambling up an
overhanging tree. Eventually after much puffing and panting, one nun gets
on top of the wall and pulls the other up too. They sit out of breath and
giggling, opposite each other.

Sister Maria then says, "Oh, sister Geraldine, this makes me feel like
a commando!".

"Me too, sister Maria, me too, but where the hell are we going
to get one at this time of night!?"
