Cats have a long history of being funny without actually doing anything for the joke. They don't need costumes, elaborate setups or unusual situations. Sometimes a cat just needs to sit in the wrong position or look at the camera at exactly the right moment.

The cats in this collection are perfect examples of this phenomenon.

Some are caught with expressions that make them look confused, surprised, annoyed or completely lost. Others are sitting, stretching or lying down in positions that somehow make ordinary cat behavior look ridiculous.

A few appear to be staring directly into the camera without any particular reason, while others have been photographed at just the right moment to capture an especially strange face.

Most of them are probably doing nothing out of the ordinary.

Cats have always been particularly good at this. Their faces and body language can change so quickly that a single photograph can completely alter how they appear. A cat that looks perfectly normal one second can look deeply confused the next, all because of a slightly different angle or expression.

It's one reason cats have remained such a dependable part of internet humor. They don't have to be doing anything particularly interesting. People will happily look at a picture of a cat sitting on a couch if the cat happens to look funny enough.

The 25 photos below capture that kind of accidental silliness. Nothing here required the cats to perform. They simply existed, someone happened to have a camera nearby, and the result was worth sharing.

Sometimes a cat's funniest quality is that it has no idea it's being funny.
