So I'm at my grandparents visiting them, sitting upstairs on the couch with my laptop just chilling. When all of a sudden, from downstairs I hear
THE LOUDEST fart EVER. You know how when we were little kids (or still now) we put our mouth to our arm and blew super hard to make a loud fart noise? It sounded just as loud as that, but 5x louder. Right after I heard that, I heard my grandma go "OHH GOD. I NEED TO GO UPSTAIRS"
