LOL! This has happened to me.

I was walking down the street once when I locked eyes with a small Jack Russell type terrier. He was so adorable! The owner (who was a man) got annoyed and asked me why I was staring because "it was just a dog" to which I replied "Why, are you Jealous"?

That shut him up in a hurry.

He had a good reason to be jealous, that was one cute pooch!
