I'm a bit disappointed to hear that. There is a magnificent plotline on the TV show Slings and Arrows, attempting to get a friend's skull made into a prop for use as Yorick in Hamlet. That's based on real life: various skulls are passed down in the theater tradition as possibly belonging to famous actors[1]. (On the show, they ended up using a disreputable taxidermist.)

I had a vague notion that some day my own skull might become part of the properties of my own theater troupe. It's probably a very bad idea and it's more than half a joke, but it's a bit disappointing to hear that it's not really possible.
