Well, actually you'd say "Sag's mir, denn ich muss es wissen/weil ich das wissen muss" ;) It reminds me of a game we used to play in English class, where did a similar thing, only the other way round. My favourites were "May I give you a wheelbeat?" and "My lovely Mr. Singing club" *g*

Do you know the Rio Reiser song I stand on you? The lyrics are hilarious, check them out.
