He's real to me!

Scientist claims Nessie is, in fact, a bunch of swimming circus elephants

I like this explanation, because it's silly and has the circus in it. I wish more scientific explanations had elephants or the circus in them. Wouldn't that be delightful?

However, on a more serious note, Ogopogo still exists, and there's nothing you can say that will convince me otherwise. Unless it involves elephants...or the circus. Or Gary Oldman.
