* Sans at Sans' favorite restaurant* Sans: Hey, Frisk, what do you eat today?
Frisk: One knife, plz.
Sans: Ok, one knife, plz.
Waiter: You eat a knife?
Frisk: Yes.
*Waiter asking for one knife*
Waiter: Here you go.
Frisk: Thanks you.
Listen up, buttercup. This joke is all about Frisk, that little rascal from Undertale, ordering a knife at a restaurant. It's funny 'cause who the heck orders a knife to eat? Like, are you gonna stab your steak... or yourself? You ain't the sharpest tool in the shed, are ya?
