Dorothy: Rose, what are those pills for?
Rose: The doctor prescribed them when I wrenched my back.
Blanche: I didn't know you'd hurt your back.
Rose: Oh, it's an old farm injury from St. Olaf. I'll never forget when it happened. It was time to plant the crops, but after 17 years of pulling the plow, poor old Bessie was worn out.
Dorothy: Why didn't you just get another mule?
Rose: Bessie wasn't a mule. She was a big fat lady who pulled farm plows for a living.
Blanche: For God's sake! What about tractors?
Rose: Well, come on, Blanche. If she was too old to pull a plow, how could she ever pull a tractor?
