I saw this on both Steph's and Patrick's blogs, and took the quiz. Here are my results:

You Are a German Shepherd Puppy

Intelligent, quick witted, and a bit aggressive. You've got the jaw power to take a bite out of anyone you choose.

(I was skeptical at first because Steph is a German Shepherd, too, but Patrick is a Golden Retriever, so obviously the thing is calculating something.)

I also thought that some of the other quizzes on that page sounded like fun, so I investigated a few. I especially liked What Kind of American English Do You Speak?. (Some of them, like the Mexican name one, are just silly.)
