Smiley Faces

I find it funny how many different ways there are to type a smiley face. I mean, really, think about it.

There's the colon, dash, close parentheses.
:-)
Or there's the colon, close parentheses with no dash.
:)
There's what I think of as the "winking" smiley face: the semicolon, dash, close parentheses.
;-)
Or there's the semicolon, close parentheses with no dash.
;)
There's the equals sign, capital D.
=D
Or there's the equals sign, close parentheses.
=)
There's the semicolon, lowercase O, close parentheses.
;o)
Or, if you want to put a shocked/surprised type spin on it, there's always the colon, dash, lowercase O.
:-o
And for an even more surprised, bigger mouth, there's the colon, dash, uppercase O.
:-O

And if you want to make it a frowny face, you can change any of those close parentheses to open parentheses and, viola!, your happy face is sad.

And anyway, who decided that smiley faces should be left to right, eyes-nose-mouth? Why couldn't they be mouth-nose-eyes? Like so (-: And how in the world is it possible for that smiley face (which happens to be just as sideways as its counterpart that is typed the other direction) to look upside down?!?

Okay, enough of my random ramblings. What's your favorite way to type a smiley face?
