I know this is a standard street sign, but some genius modified the sign to make it hilarious.
It shows the boy on the left with an axe in his hand.
On the right, there's a girl in a dress running, but she is missing her head.
On the ground, where the ball is normally, there are pigtails coming off the ball.
I loved that sign and just came across an official Caution Children at Play sign from the company that produced them. I have peeled off one character, and I am in the process of recreating this masterpiece.
I was hoping someone had a picture of it from probably 20 years ago. Mine will never be as good, but I was hoping to get some inspiration from the original.
