You know how cigarettes come with health warnings on the box? Well, one of the warnings used to be "Cigarettes cause impotence", and since I was a kid and didn't know what "impotence" was, I assumed they just made a spelling mistake and meant to write "Cigarettes cause importance". I thought it meant that if you smoke cigarettes, it would make you more important. Which I thought weird, since being important is a good thing.
