AC pranksters!

Haha.. I was just talking to Selena and she told me about some AC prank stories her father went tru! It's really silly how we AC guys do pranks!..
OKok.. in my era there was this greatly executed prank! First Class!!

Okay, do you know Austin Power's catch phrase?
"O behave".. haha..
so well, this guy wanted to suan Mr Lenn- the famous or infamous VP.. haha.. so he drew the words
"O Behave Lenn" Across the school field!
Back then, the bleachers did not have any wierd shelters so everyone from the classroom could see the words!
It mysteriously appeared one afternoon.. Hmm....
And it stayed there for a couple of days or weeks.. I can't remember...
The culprit was never caught..
But Mr Lenn was a great sport! He was amused and wanted to congratulate the prankster!
Haha.. so how did the prankster do it without getting caught?

It was said that some guy used weedkiller to write the words on the field on a weekend or something...
And when the grass finally died, the words slowly appeared!! lol!
And the school could not do anything about it! they couldn't paint it green, nor could they dig out he dead grass.. lol.. all they could do was to put fertilizers in the hope that the new grass would grow quick!
haha.. that was a good one...
