I know this ain't science, et. I'm just wondering and considering various mammals that it could be argued are dumb-as-dirt.

Now chickens seem to be pretty dumb, although I've read about how smart they are. Ha! As if! But bird brains--though I certainly respect bird brains--have been made light of many a time, even if erroneously.

But back to mammals. What is a good candidate for a dumb mammal, even if also an erroneous proposition?

I had a pretty dumb dog once upon time. You'd tell that dog to sit and that dog would lie down. If you said, "No, sit!" That dog would roll over and suddenly get up and put its paws on your shoulders. It would do everything but sit. It would go through all kinds of tricks while I asked it to sit. I sure laughed at that dog a lot. Maybe it just liked the sound of laughter. I don't know. It was a great dog, though pretty dumb. The reason it was a great dog is because it was affectionate, and affection carries a lot of value in my book.

But back to truly dumb mammals. Which one is probably the dumbest?

It wouldn't be the shrew. I'd expect shrews to be shrewd.

Lemmings? Are lemmings pretty dumb compared to other mammals?
