It reminds me of and I don’t know where I read it at but there was this guy who was trying to sell his pet rock in Africa. And told the buyer it keeps lions away. The buyer asked how does it work. The seller simply told him you do not see any lions do you and the buyer bought it.

It could be a joke that’s been around forever, but I know it from The Simpsons: https://youtu.be/4GzMizVAl-0
FWIW, I think I remember Bert and Ernie doing this in Sesame Street, though I can’t seem to find a clip at the moment.
