There is a theory that the expression "to take the mickey" -- to make fun of -- is derived by rhyming slang from "take the mickey bliss"<=="take the piss".

Does anyone have any evidence in support of this notion? I have no idea what "mickey bliss" means. is it a known phrase in UK slang? Any idea where it comes from?

And does the expression bear any relation to the reputation of the Irish as fast talkers?
