Reminds me of a story I heard from a whale-watching tour.
This boat in particular was in Puget Sound watching the orcas. It's very common to see pods of orcas hunting harbor seals. These orcas were chasing a seal back and forth around the boat, when it hopped up onto the back of the boat.
The pod was zooming around the boat, trying to get to the seal, meanwhile the guide is trying to get the seal off the stern, kind of nudging it with his foot. He's afraid the whales are going to capsize the boat trying to get the seal. The seal gives a look like "I ain't going back in there", and just hisses at the guide. Finally, the captain guns the boat, and does a few turns until the seal rolls off the stern.
