In UCB's monthly show, Gravid Water, an actor and improvisor are paired up. They do not know who they're paired up with until the night, nor does the improvisor know what play the actor will be reading from.
Here Aubrey Plaza (actor), talks about wanting to make out with a boy. Amy Poehler (improvisor) places the scene in a fast food restaurant, eventually closing it up to practice making out with Aubrey.
EDIT: The list of plays for the night can be found here.
Thanks to mbrendanaquitz for sharing, since I never seem to get a copy.
