I used to "wish on" dandelions as a child, when walking to Sainsbury's with my mother and older sister. I always assumed it was just us.
I've never seen the advertisement Kraftie mentioned. Having all my favourite TV shows and films on DVD, and not having a TV licence anyway, I don't ever get to see TV adverts. I don't do Netflix, either, because no decent TV show has been produced in the past ten years.
Have you read Wittgenstein's Tractatus?
