Disclaimer: I don't own Yu Yu Hakusho or any of the characters, or rainbow monkey or Kids Next Door. I made this story when I was spazzed out.
It all starts in another dimension, in a place called The Yu Yu Hakusho Boys Locker Room. Hiei walks in after a long day sparring with Urameshi and Kurama. He goes and takes off his shirt. As he takes off his pants there is something weird with what is under his pants. Hiei has RAINBOW MONKEY BOXERS?!?!?!? Well that was quite unexpected. We should probably just turn away now, but what is this? Yusuke just burst in. Hiei looks at Yusuke with a embarrassed look on his face. "Uh I can explain, and um what are you looking at!" he exclaimed at Yusuke. "Oh my gawd!!" Yusuke exclaimed."I can't believe what your wearing! This is hilarious, wait till Kuwahara, and Koenma find out! Ha-ha!" Yusuke said turning to get his friends to come see what he just witnessed. "You will do no such thing!" Hiei exclaimed turning Yusuke around and punching him across the face. "What the- what's your problem Hiei!" Yusuke exclaimed running and punching Hiei in the stomach and face. Hiei starting hitting Yusuke, and Yusuke started hitting Hiei. They kept fighting when all of a sudden Koenma, Kurama, and Kuwahara walked in talking. They all stopped talking when they saw the sight in front of them. Yusuke held Hiei in his arms giving him a nuggie. "Well what now little man! You still want to give me crap?!"He exclaimed. They both looked to see Koenma, Kuwahara, and Kurama staring at them. They both stood up and looked embarrassed."Uh we can explain!"They both said at the same time. Kurama, Koenma, and Kuwahara laughed at them.
