There was that scene in Godfather where a movie mogul, played by John Marley, refused the Don's offer and ended up with his prize horse's head in his bed. Here's an actual business enterprise based on the idea that it would be cute to send a stuffed severed horse head to josh your buddies. Likely response after you've spent your $70: "Heh. Oh yeah, from that thing in Godfather..."
This isn't obscure enough. How about a Faces-era stuffed John Marley head? Or a set of two stuffed heads--Marley and Gena Rowlands? Better yet, Marley and Richard Backus, as Andy from Deathdream. Of course, with two heads, it would be $140, but what a fine, fine use of money.
