At least the whale didn't blubber about it.

You know what they say about fish stories.

I would attribute the whale "shaking its head" to it trying to dislodge the diver stuck in its mouth. It might not have been a head shake like humans do, but it can't exactly reach in there and pick its teeth like we can when we have an undesirable stuck in there.

His sister, Cynthia Packard, originally told the Cape Cod Times that her brother broke a leg, but he said later that his legs are just bruised.

This is what stands out to me.

It is (IMO, of course) a plausible story. But, key changes to details like this are often 'tells' that the story may be BS.

I don't know if the story is believable, as I am not a Cetacean expert. According to Google, "Humpback Humpback whales feed on shrimp-like crustaceans (krill) and small fish, straining huge volumes of ocean water through their baleen plates, which act like a sieve."

I don't know if it's really plausible that a filter-feeder like a Humpback could physically ingest a human, even by accident (although, looking at that YouTube video on Page 1, it seems plausible). It just sounds hokey. I am not saying the guy is a liar, but I do have my suspicions. . .
