The hilarity!
You caught the spirit of exactly being in a public bathroom. Indeed, true.
It really made my laugh at certain points.
What I don't get is the last guy complaining about the graphics. Seriously, if it's meant to be funny, and not serious, graphics doesn't matter! Who cares about graphics if it makes you laugh...? I don't understand how such a thing can make it worse.
Sure, if it's a action packed kind of flash, I'd expect the graphics to be very good, and something that the author would've worked hard upon, but in this case, it doesn't matter.
And, the graphics aren't that bad. They're quite okay.
