Underfell! Sans - I'm just your problem

This video came out of nowhere. All images from Tumblr,. DeviantART, and Google Images. Also, the reason why I chose this song for the skelebros, is because they're dysfunctional in this AU, and from the fanart and shit, Sans seems to disobey Papyrus. The dialogue during 2:46 - 3:01 is what I imagine Sans telling Frisk in the forest, after they get out of the ruins.
