On Jeopardy! yester-day there was a clue stating that "He that lies down with dogs shall rise up with fleas" is among "Ben Franklin's wisdom" in Poor Richard's Almanac. The clue made it seem that Franklin coined this phrase, but according to The Oxford Dictionary of Quotations, it's a proverb dating from the late sixteenth century. In any case, it got me thinking about "You Lie Down with Dogs" from Eve, and this morning I realized something about the line "You lie down with dogs, you get up with fleas," which occurs at the end of each chorus.
Generally, the melody to which "you lie down with dogs" is sung descends (aside from regularly dropping down to an F, it's a conjunct descent from Eb to Bb), and there's ascending interval of an octave at the end to represent the "get[ting] up with fleas." I think it's something like:
(I'm not very confident in my accuracy of the rhythm, but I am pretty sure about the notes, which is what's relevant here.)
