Sans and Frisk marched into the bathroom. "Alright kiddo," started the skeleton, as he opened up the mirror cabinet and pulled out shaving cream and a razor, "You're no longer a small fry, and someone has to teach you how to shave." Sans took the shaving cream and sprayed a wad of foam into his hand, he then rubbed the cream around the mouth of his skull. "See, first you spread the stuff over your facial hair..."
Frisk then interrupted Sans's lecture.
"What Frisk?"
Frist pointed out Sans's lack of any hair.
"Oh yeah. Forgot about that..." Sans sheepishly rubbed the back of his skull, and looked at himself in the mirror, "To be honest, I didn't really think this one through..."
Sans then spotted Toriel walking by, and turned towards her, "Hey, Toriel?"
Toriel stopped and entered the room, "Yes Sans?"
"You got hair, right? Mind teaching Frisk how to shave?"
Three hours later...
"...and that's why I need to bunk with you for the weekend." concluded Sans as he finished telling his tale to Papyrus. Sans's head was also on fire at the moment.
Papyrus shrugged, "Well, okay Sans. But now who's going to teach Frisk about shaving?"
Sans looked to the side, "Well I ran into Undyne after Toriel threw me out, and she volunteered to do it after I told her what happened."
Meanwhile...
Undyne finished sharpening the humongous sword Alphys made for her, and handed it to Frisk. "Alright punk, now you just shave yourself using the edge of the sword. Relax, your scales will protect you if you don't aim right..."
