Watch: Breaching humpback whale shocks dad and son on fishing trip at the Jersey shore

A casual father-son fishing trip quickly turned into a whale of a good time at the Jersey shore!

Zach Piller from Bensalem, and his dad Doug, were casting their fishing line on a boat, when suddenly hundreds of fish started jumping from the water.

Moments later, the surface of the water broke, and a huge humpback whale breached in front of their eyes. The massive whale crashed back into the water, knocking against their boat.

The shocking moment, and equally surprised reactions, were captured on video.

"Oh (expletive)! I got that on video!" the man behind the camera was heard saying.

Doug may have lost his fish in the end - but it will remain a day this father-son fishing duo will never forget!
