Man, that's too funny. Years ago, I was the art director at an ad agency, and we had a client, The _________ American Bidet, and we created lots of tasteful, yet descriptive ads for this product.
When we went to PLACE these ads, we quickly discovered that talking about CLEANING this part of the body is, apparently far worse than describing its USE...

That is, we were stymied. We wanted to run the ads in L.A. Magazine, and we kept getting turned down!
We could not use the word 'toilet', 'commode' or any other reference to same...in describing just what the thing cleaned, the only phrase we could use was 'the perineal area', a phrase which 9 out of 10 people did not understand...
In short, we had taken on a client who wanted to advertise a product which
could not be advertised!! You cannot imagine the jokes we were making, trying to mask our frustration!
And the worst part of it was, it really was a great product! Far better than the one in the ad above...
