Assuming I haven't been disembowled?

ELBOW!!!

Impossible for you to lick yourself, or for someone else to lick? The latter is nothing (as letters to Savage Love have proven): for yourself, I'd say your own tongue.

Elbow.

Is this just about me specifically, or humans in general? Am I doing the licking, or is someone else?

Inga has a real hard time with my spleen.

elbows, backs of knees, small of back, taint...i could go on but this is a stupid question.

If we're talking about a person licking themselves, then the elbow. My second guess would be the taint.

They meant to say "humanely impossible."

I have this carbuncle I just can't lick.

If I've seen videos of guys deep-throating themselves, I think it's probably possible to lick your own taint. Actually, that'd be pretty damn amazing... giving yourself a rim job.

The duodenum is impossible to lick, either literally or metaphorically.  It is the most kickass of all body parts.

Tongue?

I'd say that it is impossible to lick one's own spleen.

Your tongue would have to be mighty long to reach your ear...

I have seen auto-felletio but can you really tounge clean your own asshole?

With a little effort and God's love, all things are possible.

Are they giving out free coffee for the correct answer? Because I'm thinking I could stop there on the way to work with about 50 - 70 correct answers...

Mike Huckabee @18 wins.

I can lick my elbow, so that's not it. Thanks yoga! I would say forehead.

Give me an hour - I'll get back to you.

I agree with #13 DOUG. It's not possible to lick one's own tongue. Another body part impossible to lick is the nape of one's own neck (top of the shoulder doesn't count as nape of the neck).

stomach lining?

The inside.

Geesh, didn't anyone else take Logic at University/College?

(and in case you wonder, if you can lick it, it is not "inside", it is "outside", including wounds)

The back of your head.

I think they were going for elbow, but yeah.. there are a lot of my own body parts I can't lick. There are some on other people I would not lick.

and the answer is?

I can totally lick my own tongue...with the tip, I can lick the back.

I'm going with forehead as well.

As hard as I've tried, I have never been able to lick my own soul.

Despite all efforts, I cannot lick the top of my own head.

It's a good thing nobody saw me attempt it.

@27 - um, but I can lick the back of your head. Nice shampoo, by the way, Carollani.

Confining answers to the exterior, would it be ...

Eardrum?

With exception of maybe the heart and certain parts of the brain, any part can be licked so long as you remove it fast enough...

my medulla oblongotta.

Starbucks ain't so square afterall! ew

Other Doug said what I was going to say again. It's answers like that that also make me hate riddles. HATE THEM. They all boil down to "how could this sentence also be interpreted another way?"

Well, the consensus on Google seems to be the elbow, although I did pull up a YouTube video that seems to demonstrate that it can be done... My guess is that elbow was the answer Starbucks was looking for.

Your brain.
