Rainbow Dash was quite the prankster as a little filly and when she saw her father, Bow Hothoof head for the bathroom while carrying his newspaper, she saw this as a great opportunity to play a prank on him. Without him noticing, she quickly went into the bathroom before he did, snatched the toilet paper, and then ran back outside. Once she saw him head in, she stood right beside the door with a smile of mischief and is patiently waiting for him to realize that there is no toilet paper. She always tried to push her parent's buttons but given their tendencies to praise her over everything, Bow Hothoof would probably just applaud her for being such a great prankster instead of getting mad.
