You Were Walking Down A Cold Forest In The Underground After Leaving Toriel, You Keep Walking And You Spot Random Stick But You Decided To Ignore It Suddenly, You Hear A Stick Breaking, You look Back, The Stick, Broken, You Keep Walking Until There's A Black Figure Behind The Tree That Looked Like A Short Skeleton With A Blue Hoddle Pink Slippers And Black Shorts, You Keep Walking Until You Hear Footsteps, You Also Hear A Voice

human... don't you know how to greet a new pal? turn around and shake my hand

The Black Figure Gives You His Hand, You Slowly Turn Around And Decided To Shake His Hand, There's A Whoopee Cushion Sound, He Isn't Dark Anymore, His Name Is Sans, A Funny Looking Skeleton With A Frozen Grin

hehehe... the old whoopee cushion in the hand trick. it's ALWAYS funny. anyway, you're a human, right? that's hilarious, I'm sans, sans the skeleton
