You heard a conversation between Sans and Papyrus:
Sans: "Sub bro."
Papyrus: "DON'T 'SUB' ME BROTHER! YOU STILL DIDN'T REDINTEGRATE YOUR PUZZLES!"
Sans: "Easy bro, I have done a ton of work today."
Sans: "A skele-ton."
(Drum effect)
Papyrus: "OH MY GOD SANS!"
Sans: Why didn't the skeleton go to the party?
Papyrus: Because they looked like me?
Sans: ... Sure.
sans *a'm i pune*
*piris* no.
Why does Sans like puns so much? Probably because he finds them humorous.
I don't like these Undertale jokes. They just don't make any sense.
Wait, isn't this Sans' job to make a joke?
What do you call a skeleton who went out in the snow? A numb skull!
Sans: “pokes brother with ruler”
Papyrus: Sans, what are you doing?
Sans: Measuring your patience.
Papyrus: Grunts
Sans: I like eating ketchup, don't believe me? It's ASRIEL as it gets!
UT Sans to UT pap: You FORGHETTIE the spaghetti!!!
Ink sans: umm lust? That's INKAPPROPRIATE!
Fell sans: I hate these double standards...if you burn a body at a crematorium you're doing "a good job," do it at home and your "destroying evidence."
Error sans: Every time you make a typo, the errorists win.
Sans
Fell Sans: Welp, you're BONED!
Fell Papyrus: DAMN YOU SANS!!!
Sans: Wow, seems you’re really working yourself... down to the bone!
