A list of roles assigned to me by the thespian/auteur, Julia:
Daddy
Pterodactyl (over breakfast)
Bert (she was Ernie)
Elmo (she was Zoe)
Christopher Robin (she was Pooh Bear)
Playing these roles isn't demanding: I just have to respond to her repeated questions ("What's [her role] doing?" and "What's [my role] doing?") and to stand corrected when I accidentally forget what's going on and call her Julia when in fact she is someone else.
