There was a smaller billboard for a real estate agent that I would walk past on the way to work.
Big cheesy smiling face of the agent took up a big chunk of the space.
Then one day someone put large googly eyes on it. It was stupid, and juvenile and I absolutely loved it.
It stayed that was for several days before the billboard company removed them. That lasted a few days and the googly eyes came back.
It went on like this until the agent relented and had the sign replaced with one without a headshot. Which was kind of a bummer.
Certainly nowhere near Banksy's talent, but I was cheering for Googly Eye all the same.
@Sir_Osis_of_Liver @chriswho I used to pass a travel agent's office on my way to work. The window had some posters for sunny destinations, one of which featured a couple supposedly catching a fish on a fine sandy Mediterranean beach. One day I realized that the line hanging from the rod was hanging straight down and flatfish on the end was certainly 100% dead. Ergo the whole thing was staged and completely fake. Amused me every time I passed.
