I remember the Scrubbing Bubbles....
I was traumatized by those commercials because in the end they went down the drain to their deaths.
Yes, I can see how that commercial might have been traumatic for some, as the burbling bubbles all plunged to their deadly destiny...
(That commercial might have been distressing for claustrophobic individuals too, as they pictured the bubbles being confined in that tiny drain pipe, heading down, down, down...)
