Buffy the Vampire Slayer (I had to secretly stay up to watch the reruns at 02:00 with the volume below a whisper)
Goosebumps books (I once set my blanket on fire while secretly reading with the blanket draped over my lamp)
The Internet
Shaving my legs (my, wasn't I the most popular eighth grader as a result)
As for any DVD or VHS that had an M-rating, they were subsequently cracked or recorded over... this was the law in my home 'til I finally moved out at 20.
