A childhood belief about creepy crawlies

When I was very young, I saw my grandmother preparing a package for mailing. She was using the kind of tape that must be moistened to make it stick, and that must be the first time I'd ever seen that kind of tape (at least knowingly). She was licking the tape. When I saw her do that, I got very scared and cried out, "Don't lick the tape!" "Why not?" she asked. "You could catch tapeworms!" I replied. She and several other relatives got a good laugh at my expense. Turns out, ever since I'd heard of tapeworms, I thought one caught them from tape. So for quite some time, I'd been washing my hands thoroughly after every time I'd used or handled any kind of tape. And yes, that included audio and video tapes, as well as all kinds of sticking tape.
