Spirit week ideas?

So on Tuesday, we need to dress up as something or somebody "worthy". The ideas monarchy, cops, judges, military, etc have already been taken. Does anyone have any other ideas that will stand out?

On Wednesday, we need to be something or somebody that represents unity. Ideas like twins-quintuplets, and sports teams have already been taken. Again, like tuesday, does anybody have any ideas that I can dress up as? Thanks :)
