Smilies and parentheses.

Something I've always wondered about.. if I open a parentheses, and then want to end the parenthesized portion of text with a smiley, do I have to also close the parentheses?

 

Having two close-parentheses would be correct, since the first one is the mouth of the smiley and the second is the actual close parentheses, but “:))” also looks like some strange kind of smiley. 

 

So which do you prefer:

 

  Hello (This is a test :)

 

or

 

  Hello (This is a test :))

 

I'm only really wondering since I upgraded my forums and the new version of yetanotherforum.net supports smilies.  I don't have any smilies installed, so I don't get to smile anyway, but if I did..

 

So if you have an opinion please post it to my shiny new forum.  Thanks.  :)
