A pod of Orcas, or killer whales, came up behind the boat as it traveled in the Pacific Ocean, and began chasing the boat, playing in the boat's wake.
The whales were able to keep up (obviously), and the people in the boat seem to be enjoying themselves.
The boat's passengers filmed the unusual wildlife encounter and posted the video online about a year ago, but the footage surfaced this week via WLIX and is making the rounds on the Internet.
