A boating excursion off the coast of Baja turned comedic when a whale takes the sight-seeing trip personally.

From YouTube:

Sometimes in life you need a wake up call. We went whale watching on the Baja this weekend, for an excursion as a part of the Live Different Academy program and unfortunately, Chelsea got smacked in the head by a whale's tail. Luckily, she was fine and we got it on video!
