Adorable video: Animals show their love for zookeepers

WANT to know the secret to happiness? Okay, I'll let you know: become a zookeeper.

The Australian Reptile Park put together footage of their zookeepers with their charges to celebrate International Zookeeper's Day.

And the video is proof that zookeepers are indeed the happiest people in the world!

The footage shows the park staff laughing and smiling as they spend time with some of the most adorable creatures.

The staff are even able to break a smile as they tangle with giant crocodiles and venomous snakes!

International Zookeeper's Day was started to recognise the "valuable contribution zookeepers make to the care and conservation of exotic animals" and is marked every year on October 4.
