'bye, bye...' [now a linguistic brouhaha]

My great nephew [or 'grandnephew' depending on your linguistic style] saying farewell to his 'daily dump':
'bye, bye poops; have a good day in the pipes...'

Now it is reported by the mother that the correct quote would be 'have a good dream in the pipes...'. This could become the doctoral dissertation that I never did: "Grandmother vs Mother in Quotable Quotes"
or "Whassup wit de toilet tawk? [Caregivers' Bridging the Gap in Male Developmentally Correct Language Acquisition"]!

Now there's a positive attitude!
