When My brother Kenneth was about 6 (I was 12) I had told him, as we were around a bunch of roosters that when they say, "Cocka-doodle doo" they were in fact saying, "Kenneth is a poop". He reciently told me (he's now 19) that he was convinced that's what they said, and had thought that for at least 8 or so years after!!
