Specifically, jack-o-lanterns. It occuurred to me, that we replicate human heads by carving in the equivalent of a face, then cutting open the equivalent of a scalp, pulling out the equivalent of brains with a spoon, and putting in a candle. Taking out the equivalent of brains, to attempt to replicate a human head. Strangely enough though, halloween (and jack-o-lanterns) is generally more often done in america. The US. 'nuff said.
