"As dry as a Nun's ****"

This shows how depraved we have become!
I first saw that in the cartoon strip "Barry McKenzie" in Private Eye in
(what?) the early 70s(?), when he introduced us to "As dry as a nun's
nasty" (he pronounced it narsty of course)[1].

And "He was up her like a rat up a drainpipe."
