Iron Man is cool and all, but underneath that billion dollar suit of armor, there is a man.
A mortal, alcoholic, human man. And, that man, as men do, sometimes has to shit. Now,
what if he's in the middle of a colossal battle, and in the midst of the violence, he finds that
Mt. Vepooveus is about to erupt?
Well, it stands to reason that he thought of that when he designed the suit. I imagine
he relieves himself much like the astronauts do. That said, I think, just to add insult to
injury, this should be just one more weapon at his disposal. His armor should come with
an ass mounted repulsor powered turd cannon which simultaneously evacuates the
suits waste storage unit and fires the contents toward a target at an alarmingly high
velocity.
After his foe is vanquished, Stark could say something witty like "it looks like
you just had a shitty day, pal."
Oh, and just for chuckles, and to add one more reason to wear the suit 24/7,
his visor could project a seemingly real image of Megan Fox (any self respecting
geek who doesn't know who she is obviously sucks sour frog ass) inside the helmet,
and it would work in tandem with a crotch mounted...stimulation...device.
