Great lines:
Aeryn: “She gives me a woody ... (sees John’s expression) ... a woody – it’s a human saying, I’ve heard you say it often when you don’t trust someone or they make you nervous, they give you ...”
John: “... willies! She gives you the willies!

I seem to recall hearing somewhere that woody in certain contexts is a rude expression in Austrailia.

Yes, that's the point. Hmm, how to avoid being indelicate. Here goes:
The willies, while meaning the creeps, is also slang plural for a gentleman's trouser equipment. (And I don't mean the Corby Trouser Press.)

woody on the other hand is slang for that same equipment when the gentleman loves his wife very very much.

Not only that, Sophie, but "woody" also refers to that equipment in an... err... excited state.

Not sure if you're joking, but that's what I was trying, with exaggerated delicacy, to describe.

Ah, I misread your first post.

As Emily Latella would say... "Oh, that's very different! Never Mind!"
