A Funny Thing Happened on the Way Home

So I'm driving home tonight and I see a new road sign near a construction area and, since it just started raining, I squint to read it. The sign reads, "Clean Water Falling."

I pause for a half second to let that sink in as rain pours on my car.

I live in Northeast Ohio. Near Cleveland. Clean Water Falling? You've got to be kidding me.

Although this person would apparently agree with the sign.
