The ultra-official explanation for room temperature IQ people is, that it helps people to throw away cup with the bottle into the recycle bin.
And no, don't ask me, how that logic is supposed to work. It is either a retarded shit test made to make it obvious who are people willing to have a cap in their eye, and people who will tear the cap by default (to make the divide among people and NPCs even more obvious).... or it's something politicians made, because they are too stupid not to lose it.
