   Summary

   So you got woken up in the middle of the night by your new neighbors... no biggie! You're sure they're just excited to be in a new (cheap) apartment. So you decide to introduce yourself to them when they get settled in.

   But to your surprise, your new neighbor just so happens to be a skeleton!

   "Oh!" You say, surprised by your neighbor's appearance, "Uh hey! Welcome to the unit, I'm your neighbor"
   "oh! hey i'm sans" He smiles, lazily copying your initial reaction.

   You hold your hand out to shake, he looks at your hand for a moment before accepting it.

   when all of a sudden...

   PPPPPPRRRT!

   Was that a... whoopie cushion in his hand?
