Way back when, a long, long time ago, when our 18 yr. old was about 5 or 6 and hadn't started down the genetically inclined dark path of night owl behavior, he liked to arise early on Saturday mornings and watch cartoons, while his dad and I liked to sleep in a wee bit later. Things are all reversed now, but, alas, that is a different entry for another time.
We were good parents and asked him on what shows he was watching. Sonic the Hedgehog was good. Bugs Bunny was good. All the shows he listed off were known to us and fine for him to watch... with one exception:
We didn't know what Coal Man was, but it sounded educational. We quizzed our son on Coal Man. Was it a good show? Would we think it was good for him to watch?
He assured us that Coal Man was a good show and that we would approve of it.
Then one Saturday my husband and I were both up early enough to see Coal Man.
Coal Man was really Conan, as in Conan the Barbarian.
