Everybody thinks my neighbour is doing some sort of Nightmare Before Christmas thing every year, but really they just don't feel like doing two separate front yard displays for Hallowe'en and Christmas, so come November 1st they stick a Santa hat on the skeleton and call it a day.
I sometimes wonder how often archaeologists trying to make sense of the traces of some ancient ritual end up completely wrong-footed because the only surviving example we have to work with was performed by somebody going "fuck it – good enough".
