"The Regina Monologues"
where the Simpson family is waiting.
He invites them to see his show, the name of which cannot be spoken without incurring really bad luck.
Homer, naturally, cannot help but say the name, and an anvil falls from the sky, landing on Sir Ian's left foot.
Homer utters the name again, and lighting strikes . . .
with electrifying results . . .
Somehow, like all good cartoon characters, Ian survives this onslaught . . .
only to be seriously crushed . . . .
by a falling theatre marquee.
