You’ve Seen It Now
Having skimmed half of this list, we can safely conclude that boredom drives most of the humor in these funny signs. Why do you want people to stop at your character and read it? Knowing that ten or so people laughed at your joke? It’s not as if these signs have ever done anyone any harm. It could be that this simple joke about a cat we have seen was enough to make someone’s day somewhere.
Don’t Make It Weird
Even if it’s just a joke, the truth is that it’s difficult to tell if this sign is serious. The reality is that when someone meets a stray dog, they can get attached to him, and parting with him can be tricky. We know that adopting a dog is lovely, but the key is to remember that someone already has a family. But you can always have your own- with this sign!
