How about a "Strong Badiumy" icon? You know, an Adium duck with the head colored like SB (but with the bill still showing) and barebreasted and winged except for boxing gloves on the ends, and a black pant cover on the bottom.

Don't get me wrong... the Strong Bad icon you made is cool, but I like the idea of making it more obviously Adium whilst still paying homage to the coolest guy in the Universe.
