"Hehe, I got an idea," said John. "Pass it to me."
Sean did as he was told, tossing the wish-granting necklace to John.
John squeezed his fingers around the medallion for a few seconds. "You might wanna stand a bit back."
"What'd you do?" asked Jean, stepping back a few inches.
A look of panic passed over Ken's 'face' as he heard a deep gurgling of digestive unease. The horse which controlled Ken's life so utterly lifted up its tail as a fiery hot explosion of wind bubbled out of its anus, which just so happened to be Ken's mouth. It smelled and tasted worse than any Ken had endured so far, and he could already feel and heard more rumbling to come out next.
"Gave his owner a full tank of gas," quipped John, grinning as a particularly long and rank fart erupted out of the horse's moist crack, making it flick it's tail unglamorously.
The two boys started laughing as they watched Ken deal with his master's flatulence.
