Here are some specific ones I'd like to see:

1. A Picketing Line of Smileys holding "Go Home" or some such walking in circles raising and lowering their signs. The forum posts ahve a limit of 10 smileys, this could count as 5.

2. One playing the world's smallest violin.

3. 2 Smileys high fiving.

4. Cartwheeling Smiley
