First - the formal one:

Hey.. Whazzup Dude? (or Dudess as the case may be)

Then for the umm nervous when in the presence of limitless Wisdom, we also permit:

Oh Thou whose boots I am unworthy even to lick, whose brilliance dazzles mine eyes even when closed, with the brightness of A Thousand Suns: In abject supplication I grovel before thee and ask, "What sayest Thou regarding ___?"


HTH
We are very pleased to have been of service to a needful world.
