I've done more than a dozen theater productions since college, and three of them were Neil Simons: Broadway Bound, Barefoot in the Park, and Odd Couple. They still have the recognition to pull in audiences, and they still work. Mostly. There are some cultural references that have to be changed, but the comic cadence is still there. It almost doesn't matter what the words are; that rhythm of comedy is airtight.

I was mildly amused by the first two segments. The Twilight parody, however, was awesome...when they stuck to the source material. As soon as they deviated into the stuff about Edmond being Dracula's son, they lost me.
