When two irate bull elks entangled their antlers while fighting, they were forced to sleep together for a week -
...PEACEFULLY...There was no other way.
It all started when a Nevada rancher discovered them with locked antlers, and still in fighting mode; so he called Rangers to the rescue.
Rangers came, they tried; but the Elks sped away together, managing lock step with antlers, too, still locked.
Rangers searched wilderness for a week, at last finding them exhausted, lying on the ground, antlers still entangled.
...and, of course no longer embattled.
Finally, tranquilized and their antlers untangled by Rangers, the Elk managed to get up, restore balance, and scamper off in different directions.
