It seems like a lopsided match-up, goose versus gorilla, but things aren't always as they appear.
In a video uploaded to YouTube, which has already been viewed more than 39,000 times, a goose and a gorilla go head-to-head -- and it's the gorilla that ends up retreating.
After a really good stare-down, the goose then takes off towards the gorilla, flapping its wings in an aggressive manner. At that, the ape backpedaled feverishly, not wanting to test the bird's limits.
Watch the entertaining video because it's Friday:
