Flipping Ears Inside Out

Accidental ear flippage, often a result of rolling around like a goddamn maniac, is almost exclusively reserved for dogs with floppy ears, much like the one pictured. Occasionally a cat or a pointy-eared dog will have their ear flipped, but it's a rare citing, like a bald eagle or a sober fraternity.
But a human having his or her ear flipped inside out isn't just rare, it's impossible. And if it does happen, seek medical attention immediately...or make a video and put it online. The only real advantage to this ear flipping ability dogs have is that it doubles their "Holy Shit You Guys, That's So Fucking Adorable" factor (a factor that is already five times higher than a human's, on average), making them more likeable than us without any effort on their part.

Scratching an Ear With a Foot

Listen, I don't care if you've been doing yoga since you were a fetus, because even if you are physically capable of scratching your ears with your foot, you would never do it in public. Talk about inappropriate. Hey everyone, my ear itches, so I was thinking you could all check out my crotch while I sit on the floor and scratch it in a very compromising position. On top of that (which is a place I wouldn't recommend literally getting on top of, just figuratively) it's impractical. Why not just use your hand? It's so much easier, and doesn't put your hamstrings at risk.
But none of this is true when it comes to dogs and cats, because as far as they're concerned, there couldn't be an easier and more polite way to get rid of that ear itch.

Ear Lifting

Dogs are the main culprit here, although cats and a few other small animals shift their ears around on occasion. But whenever dogs hears something super sweet or super lame, they lift their ears up as if to say, "look what I can do with my ears, humans. Can you do this? No, you can't. Aaawww, that's too fucking bad. Oh wait, you can wiggle your ears a little. Neat party trick, but you can't completely change their angle so as to gain significantly better hearing, can you? No, I didn't think so. Also, how good is your hearing anyway? What's that? I couldn't hear you. Just kidding, I could totally hear you whispering, 'my hearing is really shitty compared to yours, dog, because you have such great hearing, dog. You're the best.' Listen (if you can, with your crappy immobile ears), if you rub my belly and take me to the park, I wont tell anyone about your shitty hearing, okay?"
At least that's what the ear raise says to me, but I may read into my pet's actions too much...nah, I don't. Not at all.
