I pulled this off of a list of "funny sci-fi". It mostly failed to deliver on the first part, and took over half the book before we ever got into the "sci-fi" aspect of the book. It wasn't a very bad novel; just not quite what I was expecting.
My favorite part, however, was when they discovered what whales were saying. After learning that all whales are named Kevin, the conversation goes something like this:
"Hey, Kevin! Fish!" "Fish?! I love fish." "Hey, there's fish over here!" "Oh boy, fish!" "Hey, Kevin, how 'bout that fish?!" "Yeah, Kevin, let's get some fish!" ... and so on.
