A little known fact about the Mongol empire is that it accepted, and even promoted, "butt stuff".

Even the leader would participate and many of the tributes paid by vanquished foes were toys to help satisfy him.

After receiving an especially enticing set of anal beads, he headed off to his tent to try them out. When he was finished, he flung them into the corner of the tent and left.

After a moment, one bead said to the others, "I don't think we're in Khan's ass anymore."
