Finally, Finally I've tried the AssHole flushing closestool @ FujiXerox. The 1st time I saw the machine, it reminds me of MS flight Simulater. Complicated!
But it feels a little bit strange. Though I've turned it down to the smallest gear, it still feels like somebody's putting a finger in your ass. Can't imaging what's gonna happen if I turn it ON! Maybe I'll fly right up from the "Pilot's seat".
