Herros pants

Most people who've seen a few episodes of Gundam Wing a few times may notice the main character, Heero Yuy, wears disgustingly tight spandex pants (ie. Those tight stretchy pants seen to above.) How can something so tight be comfortable? Is it some form of protection gear or is it because Relena likes it that way?
After a series of experiments and investigation, our team of researchers has come out with an answer.
Those tight pants are a form of fighting-ability enhancer. When Heero is losing a fight (ie. Getting his ass kicked), it becomes tighter and tighter and tighter (ouch), forcing him to increase his ability. When he decided to self-destruct his MS, this was because he could no longer stand the pain any further! Thus, Heero always has to win, otherwise those pants will just constrict until there's nothing left.
