He told a little kid he doesn't know to eat mushrooms.



In my opinion, the "Great Papyrus" is just an act to fool everyone into thinking he's a moron so he can get away with shit that would land most people in jail. That's probably why he's so keen on agreeing with everything Undyne says too...she's the guard captain (though he still makes fun of her). I'm not saying he's a bad person, but as I've said, he and Flowey both have a dark sense of humor. I wouldn't be surprised if Flowey told him what you were doing throughout the game; he probably told him what you were wearing too AND gave him your cell number (there's no way in hell Papyrus just HAPPENED to put in the correct sequence of numbers two minutes after you left Snowdin).



And yeah, I do remember the call about the outfit. He screws you over regardless of what you tell him. If you tell him what you're wearing and keep the same outfit, he says he told Undyne because he thought you'd be smart enough to change (basically calling you an idiot). If you change your outfit after he asks, you get this " AH YES, I BEING THE GOOD FRIEND THAT I AM DID NOT TELL HER WHAT YOU WERE WEARING. IN FACT, I TOLD HER YOU WERE WEARING <<armor>>. I KNOW YOU WOULDN'T BE DEAD CAUGHT WEARING THAT."



He's a lying smartass and by extension, the most interesting character in the game aside from Sans.
