When
somebody lets out about 22 liters of silent
gas from a very
filthy, unwashed, shit encrusted asshole and it smells Zackley like SHIT.
As Scooby Doo and the gang had another mystery on their hands, they were cruising in The Mystery machine and all of a sudden
Fred smells something coming from the way, way back and he says... "I don'
t know if it's you Shaggy, or you Scooby, but one of you has a serious case of The Zackleys" Scooby: "Uhhh?" Shaggy: "Zoinks , like, I don't know what The Zackleys are Fred." Fred: "Since Velma is a girl and Daphne is a girl and
girls don't fart, and I can see Scooby's asshole, by the process of elimination, the person with The Case of the Zackleys is YOU SHAGGY. You farted and it smells Zackley like shit. Besides, you are such a filthy looking, grimy mother
fucker, I'm sure you have a crusty asshole and you must have a load of
brown foam in your under britches because I can see it running out your pant leg. Now I know why you always wear brown
pants. MYSTERY SOLVED. You Shaggy, have a case of the Zackleys, you filthy mother
fucker."
