Diarrhoea

A little boy blows up his balloon and starts flicking it all around the house with his finger. His mother tells him to stop it as he's liable to break something. The boy continues. "Johnny!" mom screams. "Knock it off. You're going to break something." He stops and eventually mom leaves for a short trip to the store. Johnny starts up with the balloon again. He gives it one last flick and it lands in the toilet. Mom comes in and while putting away the grocery gets the urge. A diarrhea run. She can hardly make it to the toilet in time and SPLASH, out it comes. When she's finished she looks down and can't believe what she's seeing. Diarrhoea everywhere! She's not sure what this big brown thing is in the toilet! She calls her doctor. The doctor is baffled as she describes the situation, but he assure her he'll be over shortly to examine everything. When he arrives she leads him to the bathroom and he gets down on his knees and takes a long, hard look at the thing. Finally, he takes out his pen and sort of touches it to see what it might be and POP! The balloon explodes and diarrhea is everywhere. On him, the walls, etc. "Doctor! Doctor! Are you all right?" she asks. He says, "I've been in this business for over 30 years, and this is the first time I've ever seen a fart!"
