1. Funny.

But I gotta disagree with the last one about humans always looking happy. I have more than once sat on a bus at the end of a workday and noticed that not too many of my fellow passengers look very happy.

3. I knew that cats use Apple computers

But I didn't know dogs did.

4. My dog, Albert, never has to worry about where to get a good head rub

And if he feels the need to be reassured he's a "good boy" he doesn't have to worry about that either.
