Your homework for today is to read:

From the way you describe British comedy as insiders, and from what I know as an American, I would posit that these prompts would be realistic grounds for a script such that:
#1 would be a scene in a British comedy sitcom.
#7 would be a scene in a high-budget HBO-type production like "The Sopranos"
#8 would be a scene from a premise set up by reality television, potentially dramatic or comedic.
#12 would be a scene from a prime-time sitcom ("Kramer, where did you GET this box of scorched human hair? What, were they giving away free samples of scorched human hair at the deli?" At the end of the episode it would be revealed embarrassingly that the scorched human hair belonged to George.)
#13: You could tell me that this was a plot element already used in LOST or Heroes and I would have no ground to question your sincerity.
HONORABLE MENTION: I think a large number of classic European arthouse films include scenes described by #11.
