I had the above thing happen one night long ago. In the middle of the night the front book fell out of the shelf for no apparent reason. I hadn't touched it, or the shelf, in weeks. No idea why it decided to jump off the cliff shelf just like that, but I almost got a heart attack from it. 
Someone must've been watching the Jersey Shore.
I guess Jersey Shore is some especially stupid TV show?
The Jersey Shore area rose to national fame in 2009 after MTV started airing the reality series Jersey Shore. The popular show, filmed mostly in Seaside Heights, NJ, debuted amid large amounts of controversy regarding the use of the words "Guido/Guidette," portrayals of Italian-American stereotypes and scrutiny from locals because the cast members, with the exception of one, are not residents from the area.
They are basically a cast of shallow, superficial, self-absorbed idiots who are getting attention and a ton of money for being shallow, superficial and self-absorbed.
Jersey Shore Cast Quotes:
Mike "The Situation": Some days I’m Uncle Situation, other days I’m Dr. Situation, I’m Chef Situation.. Bang Your Girl Situation… I’m like a pretty deep dude.
Pauly D.: I'm over here tryin' to clean my sneaks, I can't concentrate with all this fighting .. like they're talkin' about f*ckin' relationships and my sneakers are dirty!
Snooki: I hate the ocean, it's all whale sperm. Everybody Google it, because that's why the water is salty, from the f*ckin' whale sperm.
Snooki: The staircase is really small and the bed is really wide. It's kind of like an analogy of Vinny's penis not fitting in my pinhole.
Angelina: How do you go in a Jacuzzi in a bra? And a thong. Wear a thong bikini -- that’s a little bit more classier.
Pauly D: Snooks got hit in the face again, poor girl ... somebody’s got to teach her how to fight. Or duck.
JWoww: Tall, completely jacked, steroids, like, multiple growth hormones ... that's the type I'm attracted to.
