Dorothy: I'm teaching history for an adult-education program. It's for people who never got high school diplomas.
Rose: What else do they teach?
Dorothy: The usual high school subjects.
Rose: You mean like the three Rs: reading, writing and rooster inseminating?
Dorothy: No, we just teach the first two Rs.
Rose: Fine. But you'll be sending people out into the world who don't know you can get a nasty rooster bite if you don't warm your hands up first.
