For me, he defined the role of Puck. So now it's like he's actually disguising himself as a mortal so he can walk around undetected. And it doesn't help that the woman who played Titania, Queen of the fairies, is with him (using the cruise-ship alias and disguise of Christine Albright).
Puck and Titania sometimes disguise themselves as John Tufts and Christine Albright, or even as Romeo and Juliet, as shown above.
