Whales

The ways of the learned to me are 'Greek,' And professors and such amaze me. I know, without trying, the thing they seek, Tho' I doubt if for that they'll praise me. They want to discover why whales are big, So they sail, at the risk of sinking, In ships with elaborate, technical rig, When the facts can be learned by thinking. I can simply account for the size of a whale And it doesn't seem much of a riddle It's because he's so long from the nose to the tail And in measurement round the middle.
