so, there's this expedition which goes to Brazil to look for a tribe of headhunters...they are headhunter hunters...and the leader is the head headhunter hunter..They are anxious to meet the chief of the tribe..(the head headhunter)..because he is reputed to have killed and shrunken the head of the LAST expedition, and enshrined it as the pre-eminent totem of the region..(the head head!)..so..they are looking for the head headhunter's head head....which is SUPPOSED to be mounted right above the chief's outhouse..(the head headhunter's head head's head head....)...etc....it can go on forever, I think....you just add verses
