Here's a video that straddles the line between bravery and stupidity.

Instead of observing the pod of humpback whales from a safe distance, these two kayakers were eager to get up close to take a few photos.

What they didn't count on was getting lifted out of the water by their new friends - which might be a gentle reminder to keep out of their personal space.

With male humpbacks measuring 13-14m in length and 25-30 tonnes in weight, they may well have got off lightly.
