To create this pig flying image I photographed a pig at a country fair then combined it with Egret wings photographed near my home. The clouds were actually photographed on the island of Socotra off the coast of Yemen! We also have a hang gliding flying pig, three pigs flying in formation, a pig drinking beer, and a pig riding a Harley motorcycle...hog on a hog if you will!

Pigs, I might add, while very intelligent, also tend to squeal at ear-piercing volumes. In my admittedly limited experience at photographing them, they have not been particularly cooperative and get get rather large and obnoxious to boot. Not my favorite animals to photograph! 

The idiom "when pigs fly" is a common expression used in the English language to describe something that is highly unlikely to occur. The phrase is often used in a sarcastic or humorous way to indicate that an event or situation is unlikely to happen.

The origin of the phrase is uncertain, but it is believed to have been used as early as the 1600s in English literature. One theory is that it comes from the idea of pigs being unable to fly because of their weight and lack of wings, making the prospect of them doing so highly unlikely.

Over time, the phrase has become a part of popular culture, appearing in various forms of media such as books, movies, and music. It is often used in comedic contexts to emphasize the absurdity of a situation, or to highlight the speaker's disbelief in something that has been suggested.

Despite its humorous connotations, the idiom "when pigs fly" can also have negative connotations, especially when used to dismiss someone's dreams or aspirations as unrealistic or foolish. When used in this way, the phrase can be hurtful and dismissive, implying that the person's goals or ideas are not worthy of consideration.

In recent years, the idiom has also taken on a political meaning, with some people using it to express their skepticism about certain political promises or proposals. For example, a politician might say "I'll support that policy when pigs fly" as a way of expressing their doubts about the likelihood of the proposal being implemented.

Despite its negative connotations, the idiom "when pigs fly" can also be used in a positive way. For example, it can be used to encourage people to pursue their dreams and to never give up hope, even when the odds seem stacked against them. In this context, the phrase is used as a reminder that anything is possible with determination and hard work.

Overall, the idiom "when pigs fly" is a popular and widely used expression in the English language. While it is often used in a humorous or sarcastic context, it can also have negative connotations when used to dismiss someone's ideas or goals as unrealistic. Despite this, the phrase can also be used in a positive way to encourage people to never give up on their dreams, no matter how unlikely they may seem.
