@xxSansThePUNsterxx asked How do skeletons get drunk by drinking ketchup?

Trust me. It isn't normal. It comes from drinking so much ketchup that I start to act like a fucking weirdo. Its just how I roll.

@TheUnkownGlitch asked Hey Sans, What's your favorite pun? Aaannnnddd how did you start drinking ketchup?

I don't have a favorite pun. Why? There's too many to choose from. There's so many new ones being used every day. It'd be hard to ketchup on them all. XD
Aaaaannnnddd I started drinking ketchup because my dad ran out of milk for me to drink when I was a baby. So he replaced it with a bottle of ketchup. I never drank milk again.

It all started when I was just a little three year old. I was eating my chocolate bar when suddenly it was taken from me... Let's just say, I had definitely snapped st that point. No one touches my chocolate.

The next chapter will be published shortly. See ya later.
