Likewise, 'Jack Jones' for 'own'. I don't know if it refers to the Los Angeles crooner or a later namesake.
I never get this ones: what's the point in having rhyming slang and then using something that doesn't really rhyme? There must be thousands of other words or names out there that properly rhyme with 'own', without the awkwardly unnecessary 's' sound on the end.
I sometimes use 'pen': pen and ink = stink. I'm aware this might be controversial(!), but I don't see the point in saying the whole phrase, especially when it just takes you longer; and it just sounds a bit faux and try-hard - so you'd just 'go for a Ruby' not 'go for a Ruby Murray'.
I'm also a bit confused by 'mince', though - is it eye(s) (as in mince pie(s)) or fart (as in mince tart)? I've heard it used for both!
Talking of more recent CRS, I love the development that led to £15 eventually being referred to as a 'commodore': 'once, twice, three times a lady', with a 'lady' being a fiver ('Lady Godiva')!
Also, I didn't realise that 'Aris' was a double one until quite recently. I always assumed it was just a variant pronunciation of arse, but no: 'Aris' as in 'Aristotle' = bottle; then 'bottle and glass' = arse!
