When I was a kid, I had just watched The Animal starring Rob Schneider. One day I went to a public bathroom with my dad. I saw the paper towels and copied a line from the movie, not knowing what it really meant:
"I wish they had one of those blowjobby things...I mean handjobby things...I mean hand dryers!"
My dad told me not to say that and I didn't find out why until a few years later...
