On chat.meta.stackoverflow, there's a little easter egg where text entered as
will be rendered as a moderator only tag.
We'd like to do something similar, but specific to superuser -- namely, when you type a magic string, something amusing and in-joke-y for superuser.com happens, and it's visible to the entire chat room.
Do you have any ideas for anything super-user-y we can do as an easter egg in chat.superuser.com ?
