It's interesting to me to have so many different kinds of english spoken on this NG. Now I know what "plonk" means.
What is the derivation of "...and Bob's your Uncle"? I know it means "and then you're done", but who is Bob and why is he my uncle?
In Panama, "listo y frito" (cleaned and fried) is the same as "then it's done". However, since the Panamanians are a fishing people, it's easy to see the derivation of the expression, where as Uncle Bob is not so clear.
