Blind Guardian's video for their song Mr. Sandman has three Pedo Clowns. Poor kid in the video is gonna need some serious therapy. As if that video wasn't pure Monster Clown-filled horror already...
Speaking of, the creepy old guy from the video for Metallica's Enter Sandman.
Hush little baby, don't say a word, never mind that voice you heard, it's just the beasts under your bed, in your closet, in your head.
The original rapist to appear in a heavy metal song is "Captain Howdy" from the first half of Twisted Sister's Horror-Teria, but don't worry; in the second half, Captain Howdy face some vigilante "Street Justice."
Mr Sandman in "Today's Lesson" (by Nick Cave and the Bad Seeds) "has a certain appetite for Janie in repose / he digs her pretty knees and that she's completely naked underneath her clothes". Yeah... Janie seems to be into it, but then, it's ambiguous whether she's an adult or not.
Who's the smiling stranger With his hair as white as gin, What is he doing with the children Who could have let him in?
The male singer of the "Baby It's Cold Outside" duet. Mostly for her line about "What's in this drink?"
Gets even creepier to anyone that's used to the Glee version...
It should be noted that the lyrics have the lines usually sung by a woman designated as "mouse" and those usually sung by a man lines designated as "wolf", although they are not gendered, and recordings featuring a male mouse and female wolf do exist.
Aerosmith's "Uncle Salty". Another Aerosmith example is the "Rag Doll" video, which was banned from Much Music for a scene wherein a young woman comes in and sits on a man's lap ("Daddy's little cutie.").
Mr. Lapage in Steely Dan's "Everyone's Gone To The Movies."
The Toy Master by Avantasia. Don't you be afraid, come and step inside, take a look around...
Ozzy Osbourne's "Mr. Tinkertrain" is quite clearly about a child molester.
Foreigner's "Hot Blooded" has some really unfortunate undertones; the lyrics are about the singer seducing a fan. Which would be fine, if every single verse didn't have at least one line implying that said girl is underage and a virgin. The girl is asked if she's "old enough", if she'll be ready for him to "call her bluff," he'll show her loving like "[she] never knew", and that they'll have to sneak away from "you know who" (presumably, the girl's guardian) in order to get it on. The last verse before the song fades out has a line that goes "I'm so hot for you, child." Catchy tune, disturbing lyrics.
In the strangely sinister video for the Blue Öyster Cult's "Joan Crawford", keyboards player Allen Lanier - who even looks (for this video) somewhat seedy and untrustworthy around young girls, is seen hanging around a lot of Catholic School Girlsnote who may or may not have thrown away their mascara. In one scene, as the rest of the band perform the number, the girls troop downstairs from an upper room. Pause for a few seconds. Then a shifty-looking Allen comes out of the same door, theatrically checking to see if he's being observed, then he sidles down the steps. It all looks rather suspect.
The "memetic" part may not apply to Ogden Edsl's "Kinko the [Kid-Loving] Clown." The whole point of the song is that Kinko, with his "dirty pictures" and "happy cigarettes", is at the very least a child molester and possibly a kidnapper or even murderer.
