Phrase said to people by Papa Lazarou, just before he tells them that they are now his wife... and he kidnaps them.
From The League of Gentlemen.

Quote from "The League of Gentlemen", character PAPA LAZAROU, a warped character that speaks gibberish and insists everyone is called Dave and that they are his wife. Unfortunately for anyone actually called Dave in real life they may have found that when they introduce themselves they are subjected with this quote.

General greeting used to anyone.

You say hello to dave
and hi to sue
