I just watched an Undertale crack animation. Starring Sans and Chara ft Frisk. It went like this...
Sans: WHY DID YOU KILL MY FATHER
Chara: I am your father
Sans: *drops bones and Gaster blasters* what
Chara: I meant I'm pregnant and you're the father!
Sans: *shoots a bone at Chara*
Chara: *dodges* uh what I meant was...You're pregnant and I'm the baby?!
Frisk: wtf
Turns out I was on that side of the internet again. Oh and another one, it was actually an AMV. It just showed Sans, Muffet, Toriel, Undyne, Mettaton and Frisk. Only problem is, HOLY CRAP THE SINNNN.
And another one. This one I actually liked. It was Frisk, singing Sorry by Justin Bieber to everyone. Weird, but it was nice.
