It kind of reminds me of a play when did in Grade 10. My friends and I wrote it for English class, it's a parody of MacBeth. We belonged to the drama club and we performed it a few times. Donalbain was replaced with a sock puppet, since he does so very little in the play and we ran out of a actors. So Malcolm carried him around on his hand and was like 'What's that Donalbain? Yes, we should flee Scotland immediately.' It would be sort of the same thing, I think, trying to act opposite a skull.
