Heh. This was fun to write. This one is inspired by a convo me and a friend had one day while watching Gundam Wing… How we started on this topic, I don't know. BE WARNED: This is KakaGai, because it amuses me.

"Gai-sensei!" Lee barged into his most respected teacher's room, oblivious to any warning sign that he should not enter. Though Lee was a ninja, he never seemed to catch onto things as quickly as his rival Neji. Perhaps if he had been paying just a little more attention, he would have noticed the strewn clothing and sounds of 'youth' emerging from his sensei's chambers. But let's not linger on the 'what ifs'. What Lee walked in on would have been enough to scar most people for life. Fortunately for his sanity and possibly his eyes, Lee did not quite understand WHAT was going on. "Gai-sensei… why are you and Kakashi-sensei fighting without your clothes on?"
"OUT!" Kakashi shouted while searching for a shuriken to throw at the confused Lee.
"But I merely wish to know what youthful activity you are engaging in!" Lee proclaimed as a recently found shuriken lodged into the doorframe. Lee stared wide-eyed at it and began to run, yelling, "HOW UNYOUTHFUL OF YOU, KAKASHI-SENSEI!"
Kakashi grunted and grabbed his pants in a huff.
"Kakashi, my rival, what are you doing?" Gai asked, placing his hand on Kakashi's shoulder.
"Getting dressed." Kakashi replied, now almost completely clothed. "I'm not in the mood anymore thanks to that… incident."
"But Kakashi!" Gai cried out with a hint of a whine.
"No means no, Gai!"
