Why go through the hassle of having people sign up if all the episode is going to be is dumb level after dumb level?

While I think the story should be improvised, I'd at least want it to link up with/ make sense when played with/or refered to past levels. Also it should follow a general theme so we know that Jazz, Spaz, and Lori run in certain eniroments that make sense with each other.

Long story short: This episode will 200x better if we did it with flow isntead of Pick and Use
