Why Do We Do It?

I saw this picture, which struck me as humorous, on Design Watcher, which is a blog that I subscribe to. I thought it was so funny looking--I'm a sucker for pugs--but then I wondered why people put a cigarette in their dog's mouth and take a picture?

What does this kind of picture say about the psychology of the pet owners and/or photographer?

What does my giggling at this picture say about my own mental health?

Hypothesize in the comments.
