Writings on the stall.

[Gobucki]

So awhile ago I had to go pay a visit to a Mr. John Crapper. Upon sitting down in his office, I peered about the stall and read the following:

I AM HAVING THE EXPERIMENT OF A LIFETIME
FOUL PIECES OF LETTUS IS COMING OUT OF MY ASS

I'm not really sure about this one, but I have come across a few decent ones:

HE WHO WRITES ON BATHROOM WALLS
ROLLS HIS SHIT INTO BALLS
HE WHO READS THESE WORDS OF WIT
LIKES TO EAT THOSE BALLS OF SHIT

and then there's this one...

FLUSH TWICE, IT'S A LONG WAY TO THE DINING CENTER

This is on the wall of the head at my local pub.
Everytime I am there I read it and chuckle.

No matter how beautiful she is
No matter how much she laughs at your jokes
Someone, somewhere is sick of her shit.

 

[DEBuckeye]

A classic:
Here I sit, broken-hearted; tried to shit, but only farted.
