Enjoy ^_^
In my day, we had to resort to scratching our bits of signs, hence:
"P eas in your head"
"Please obstruct the doors, cause delays and injuries"
and
"Please eat a disabled person"
I used to love doing this when I was a teenager. Even made the local paper once ^_^
The up one was AWESOME though.
How subversive.
I just steal signs.. I took a "No Entry"

I feel sorry for the schmucks who still drive in my neighbourhood.
My own entry, already posted in the Carl thread but appropriate here:

It has since been lost to The Sands of Time, but my most ironic triumph of larceny was a Neighborhood Watch sign similar to this:
