While a laser pointer can be great fun for a cat, fart machines can be just as fun for dogs. I’ve seen a few videos that show dogs getting confused by the sound of fake flatulence, but this one in particular is interesting because the dog keeps checking out her own butt to see where it came from. Was it me? Was it you? Where did that come from?

Not only are dogs man’s best friend, they’re also an endless source of entertainment. Weirdly, people can be just as funny to watch when they hear a fake fart, but at least they can verbally respond to it.
