Both these colloquial expressions are shortenings (Of Do you know something? or Do you know what?) and are used to emphasize the following statement or to introduce a surprising fact or comment. The first dates from the mid-1900s. The variant, from the late 1800s, should not be confused with what do you know or you know.
