Carl: So, how long have you girls been working?
Dorothy: That's an odd lead-off question, Carl. But actually I've been working about 30 years.
John: Boy, you must really know your business.
Blanche: Yes, Dorothy's a very experienced teacher. Everybody who's had her says she's great.
John: Let's get some drinks, go upstairs and have Dorothy teach us the three Rs. Reading, writing, running around the bed.
