Gentlemen, having found a suitably innocent "volunteer", stand her on a chair and serenade her with the following:

Alouette, lovely Alouette
Alouette, you're the girl for me
How I love your plates of meat
(How I love your plates of meat)
Plates of meat
(Plates of meat)
Aaahhh...

and continuing with ordered anatomical references in rhyming slang, up to "Barnet Fair" (sorry, can't remember most of them). Point to each item as it is mentioned.

I always managed to sneak a few extras into the final chorus that hadn't actually featured in the verses - there are so many synonyms for threepenny bits...
