Once, when I was stacking tapes I found mostly Family Guy, Mr. Bean and Futurama tapes. One of the tapes was hidden in a VHS cover and it said "Hidden Simpsons Episode" on it. I opened the cover and it said "Don't Watch!". I was concerned.
When I got back, I popped the tape in my VHS and I watched it.
First, it started with the normal intro. Then, it goes to a ten second darkness. I saw a figure going through a steep hill. A woman was singing and died.
"I died, goodbye guys!"
A Minecraft creeper showed up and said "Hi guys!" then exploded.
Then it cut to the credits. This was only one minute, thirty seconds.
