Isaac Newton's right!! Is he?

Isaac Newton once said that for every effect, there is a cause.

Well.. I was at this shopping mall....

(you figure it out where this is)

....last night at Kuching and i saw this same 'ol writings on the toilet door. To my surprise, every door of the ground and 2nd floor toilet (confined to men's room) was "decorated" with what seems to be the same words written by the same person! Feast on...
Can half way do business and watch decor somemore..wow!!! Lolz..

2nd floor men's toilet...

Ground floor men's toilet

( This photo in the middle. If u can just focus..you'd notice the same writings there, just that it has been half-cleaned)

Yea.... So i took the liberty to enter each partitioned toilet and captured it up for ya'll...
Now, we gotta have to stop and think,.. well, man.. what's the cause of this effect? Sorry, no Isaac Newton's gonna help you with this..
