Now that we've opened this can of worms . . . Let's make IMR's job a little tougher . . .
Allo (cough, cough) has a good point. This

does not have the same impression as this

. But then there is also

,

, and

. . .
Which one is what you think the smiley should be. They each have different visual impressions, and imply different emotions . . . SO, which one should the smiley be? Or, should we have more than one? And, are we missing other emotions?
We have:
Angry:

Azn:

(not sure what that stands for . . . )
Cheesy:

Cool:

Crying:

Embarrassed:

Evil:

Grinning:

Huh?!?

(confused)
Kiss:

Silent:

Rolling eyes:

(Oy vey!)
Sad:

Shocked:

Smiling:

(happy)
Tongue:

Undecided:

Winking:

But should we add other? Like:
Nice:

(angelic, as opposed to evil)
Sweating:

Tired/sleepy, etc., etc., etc.
There are hundred of options . . . . But what makes sense?
And, yes, I still have the bunnies for Easter

, that hats for Christmas

, and a nice set of tomatoes for this fall's tomato harvest festival!
