Actually maybe could be possible?
Deer naturally loose there antlers, it is usually an easy process but they sometimes have to run them against trees or rocks to get them to come off, if one got a bit too impatient and aggressive they might have fractured there skulls, deer are known to walk on there hind legs and brain damage could explain the rest. Sooo, unlikely but not impossible.
Lol, you think this is for the poors, this is so one business man in an office in Tahiti can generate infinite videos and finally monopolize the welth of the content creators into the billionaire class
