EoFF definitely got me stuck on xD, and I still use it frequently. In instant messaging conversations I use far too many text emoticons for my own good, but it makes me feel like an individual 'cause all my friends use all the crappy default smilies.

I did steal a custom smilie for xD from someone here. It was actually pretty good, but I don't think I have it anymore nor do I remember off whom I nicked it.
