You know, sometimes there just needs to be a match to light the fire. Supposedly (but indeterminately) Clark Gable wearing no undershirt drove undershirt sales down 75%[0]

I reckon an episode Modern Family or Community where this type of toilet/bidet is a positive driver of the comedy would bring in a lot of sales for bidets.
