Actually a hooker that's good at Hoovering is someone folks will pay extra for.
I'm not going to ask how you discovered that. ;)
And the best reason to take down the side isn't to spare women's dignity, but rather to spare us all from constantly having to endure a very bad pun.
Some of the fun of signage
is the pun factor, good, bad, naughty, or otherwise.
Back in the 1970s, there was a public service campaign to promote child safety in cars. The image was a kid in a seat belt; the language read,
"Have you belted your kids today?" The anti-child abuse crowd didn't appreciate the pun and the signs were taken down. William Safire noted
it in his
On Language column in the Sunday
New York Times, and finished the column by writing, "I have pasted a sign on my
dashboard:
BELT THE KIDS! It promotes safety and keeps a few passengers in line, too."
