Two monkeys were filmed jumping onto the head of a photographer knocking off his hat.

The man was taking pictures of the primates at an annual 'monkey birthday party' at an ancient Buddhist temple in Lopburi, Thailand, on November 25.

One of the animals leapt from a table and knocked off the photographer's hat, before becoming fascinated with his sunburned bald head. A second monkey then also leapt onto the man's head, where they sat eating pieces of fruit.
