Bud and Tippi Dink are the next door neighbors of Doug Funnie on the show Doug. A claim has recently come to my attention that the Dink's are so named because Dink is also an acronym D.I.N.K. meaning "Dual/Double Income No Kids". Essentially two working adults, typically married, who have no kids and therefore a large disposable income. The Dink's do fit this motif, always buying gadgets that Bud usually describes as "very expensive".
However, a dink can also be "a stupid or contemptible person (used typically of a man)". Now Mr. Dink isn't stupid nor contemptible per se, but can come off as quite aloof and not all there sometimes (although he does offer Doug great advice and teachable moments).
Doug originally aired in the early 1990's, and I am not sure how long the acronym has been in popular use (the dictionary source does claim 1980's origin).
So my question: is it verifiable that the "Dink = D.I.N.K." is true? I would be looking for a quote from a member of the production staff or similar "canon" source.
