Which one is really the jackass?

My daughter was visiting the other night. She called me a few minutes after she had left, and told me I had some feuding neighbors. There’s a house with a cement donkey and sign near the street. The sign says, “Jackass—->” and has the next door neighbor’s address written on it.

It’s been there a few days now. I think the alleged jackass is doing the correct thing (nothing) because it makes the donkey guy look like the jackass.

However it would be totally hilarious if a sign appeared that said, “I’m rubber, you’re glue…”
