Have you ever been without toilet paper? It's a horrible sinking feeling. Disgusting scenarios run through your head: should I squabble to safety, should I use what's in the trash, maybe my underwear? It's scary! Which is is why I'm going to pull this prank come April Fools.
It's pretty easy to make too: there's one sheet of toilet paper on the exterior and a hollow cardboard clone that maintains the typical shape of toilet paper. Instructables has the full instructions and it doesn't actually take much supplies or hard work, just some scissors, glue, cardboard and a roll and maybe an hour of time. Just make sure the person you prank can deal with the crustiness though. [Instructables]
