Coolstorybro666 dares: I dare you guys to teach them how to play cello

Mark: HOW THE HELL ARE WE SUPPOSED TO DO THAT?! I played trumpet not cello.

Baby Author-chan tugs Mark's sleeve and points to the cello.

Mark: Sweetie, I can't teach you-

She walks to the instrument and grabs the thing to play it. She starts playing Everything Stays by Rebecca Sugar and starts to sing.

Mark is amazed.
