18. Buy Your Kid A Clown Doll
One of the entries that falls under the heading I probably wouldn't have a problem with this if it weren't for *that* film, there is absolutely no chance in hell that I would subject my kid to owning a clown doll after seeing Poltergeist. But, setting aside the unlikely eventually that the doll will turn out to be possessed by vengeful spirits out to mess with me for building a house on their burial site, the fact remains that clown dolls are bloody creepy, and I wouldn't want to trigger a phobia by hoisting a terrifying puppet on them at a young age. I've got similar sentiments about ventriloquist dolls - largely influenced by the Goosebumps book Night Of The Living Dummy, but bolstered by the Twilight Zone episode The Dummy and the Ventroloquist's Dummy episode of Tales From The Crypt.
