Teach me - what is the best choice of emoticon to make sure nobody on this forum is in doubt that I am joking?

I thought the "evil" emoticon would be enough, but apparently it is possible that I might be sincerely evil. :O

Of course, this being the internet, I could also be a dog. Unless better advised, in future I will stick to the "wink" emoticon, since I don't find any emoticon for "bob head and wag tail" to indicate playfulness.
