What could be the meaning of this bizarre pictograph? It seems to us to be pro-litter! (SFist waxes indignant on the topic of litter here and here.)

Our top three possible intended meanings:

1. Dispose of this cup only in grates marked "Drains to Bay."
2. This cup turns white under the gaze of happy dolphins.
3. Palmolive softens hands while you do the dishes, and fish live in it.
