I think we've lost track of what actually constitutes a "show within a show"
I dunno how SITPWG or an audition in L5Y is supposed to count as a show within a show. And "performances" like Oom-Pah-Pah and A Wild, Wild Party aren't done in a show within the story, they're just performed within the setting of the show.
You're reminding me of people you hear at the movies asking questions every ten seconds, "Who is that? Why is that guy walking down the street? Who's that lady coming up to him? Uh-oh, why did that car go by? Why is it so dark in this theater?" - FindingNamo on strummergirl
"If artists were machines, then I'm just a different kind of machine...I'd probably be a toaster. Actually, I'd be a toaster oven because they're more versatile. And I like making grilled cheese" -Regina Spektor
"That's, like, twelve shows! ...Or seven." -Crazy SA Fangirl
"They say that just being relaxed is the most important thing [in acting]. I take that to another level, I think kinda like yawning and...like being partially asleep onstage is also good, but whatever." - Sherie Rene Scott
