Watermelon killer: Crocodile destroys fruit with one bite

HOW many watermelons does it take to clean out a crocodile's pen?

Well, there's really no punchline as none can't seem to get past big, bad Elvis at the Australian Reptile Park on the Central Coast.

And that's no joke.

The notoriously cranky 52-year-old reptile showed off his jaw-crunching power when a watermelon was rolled towards him in a recent video.

In the slow-motion footage, the watermelon is instantly eviscerated once Elvis "snapped his jaws with an almighty clap".

A cruelty against watermelons advocate group could not be reached for comment.

Now that was a joke!
