Yeah, but this isn’t just any lake – and nobody else dared jump in.
You see, it’s the home of a 3.5 metre long crocodile, which he figured out when the monster chased after him.
As is always the way with these things, an outlook managed to video it and posted it online.
It shows the man frantically trying to reach the shore with the giant croc in hot pursuit and, as it edges ever closer, you can hear onlookers screaming in the background.
Fortunately, one particularly smart spectator – probably aware that the man was about to become lunch, threw a large object at the beast – which distracted it long enough for the man to escape (and change his pants, most likely).
