The Bends
One day, Aang, Katara, Sokka, and Toph were haning around a hobo campfire and eating bugs
"Oh, man," Katara said, "these bugs are good, but they always make me pinch the HUGEST loaves!"
"Gross. I don't wanna hear about my sister's BMs!" quoth Sokka.
"I do." Said Toph, who clearly thought 'BM' stood for 'butt medicine.' She got so excited because, like Katara, she had to poop SO hard!
Not one to be outdone, Aang decided he should poop too. Even though he didn't have to go that bad. God dammnit.
Katara, unable to hold it anymore, stood up and pulled aside her skidmarked buttflap thing, and just shit all over the place.
"Whar? I don't even know what to do any- HURRRRGHHHKKKKKKK!" Sokka vomited all over the campfire
"NO SOKKA THAT'S THE OPPOSITE END YOU FUCKER!" shouted Aang.
Toph just save the chaos appear in front of her and went for it. She pooped a lot of different things, like a hammer and some nails. The other three were in awe and declared Toph the world's first shitbender.
THE END.
