Sasuke
Deidara was not the only member of the feared Akatsuki who had problems with his hair and comparisons. While the blonde's hair got compared to pineapples and palm trees, the Uchiha had it (in his opinion) even worse.
"What would you say, Karin? A pigeon, a chicken or a duck?"
Oh how he hated it.
The first time somebody said something about the shape of his hair had been in the academy. (He was pretty sure it had been Naruto; he had to make sure to kill the idiot later)
Unsuspecting little Sasuke (8) had entered the classroom, without suspecting (like the word unsuspecting says) any harm. He sat down on his seat and waited for the teacher to arrive, when suddenly somebody with an obnoxious voice yelled "Look, Sasuke's hair looks like the ass of chicken!"
And ever since, wherever he went, those comments were made about his hair.
He unconsciously touched the spikes at the back of his head and frowned.
He was sick and tired of those jokes. At first, they may have been funny, but now? Couldn't they think of something else? Not to mention that it didn't have that many resemblances with the behind of those...things (anymore). Even he had to admit that his hair style in his younger years had been a little...strange, but today, his hair was simply spiky. Nothing else. Just. Spiky.
The hair/ass issue had another rather annoying side-effect. No one could decide WHICH kind of poultry's behind his hair resembled.
It was utter torture to listen to them discussing why his spikes looked more like a duck/chicken/pigeon/etc.'s butt, rather than a duck/chicken/pigeon/etc.'s one.
But until the day the world would be mature enough to stop laughing, Sasuke couldn't do anything but wait.
(He had considered cutting his hair but decided that he'd rather listen to the hair/ass-jokes than do THAT. He liked his hair too much the way it was.)
