Thanks for tooth, jazzgirl. I'll see what that does.
Yes I did see your last post, thank you, but I am not convinced that "one" meaning a drink or a joke is a common device. In 30+ years of crossword solving I've met it only on the two occasions you have explained it to me!
My wandering mind also dredges up:
"How much is that doggy in the window?
"The
one with the waggly tail."
