One day Pikachu decided to take a shit in the Viridian Forest. It was so enjoyable, he did it on the trees, and then in the Viridian City. The entire Kanto region exploded from his electrical crap.
"And that's my tale of what I did today," Pikachu explained as he sipped some coffee in Heaven with Arceus.
"That sounded terrible!" A Pidgey exclaimed upon flapping its wings. "Why would you willingly destroy everyone by crapping?"
"Because almost everyone poops, Pidge. it's what we do." Pikachu admitted as he then charged himself with electricity to feel better, turning to face Arceus. "Can you send me back down to Earth?"
Arceus thought for a bit, the Pokemon god contemplating. "Hmm... well, you seemed to have learned your lesson... all right." He then had his eyes shine brightly as Pikachu was zapped back into the living world, with the Pidgey staring at Arceus oddly in return.
