rather not because it would be more likely a women's earring then
You simply have to click on "Show all" (it's right above the other smilies) to get more of them. If it doesn't work you should turn off your pop-up blocker. If you mean other smilies which are not on this site here at all, you have to upload them to imageshack or photobucket first and then you have to click on "Insert image" (the icon with the orange dot) and copy your imageshack or photobucket link there. Hope that helps.
