Two elderly couples were enjoying friendly conversation when one of the men asked the other, Fred, how was the memory clinic you went to last month?" "Outstanding," Fred replied. "They taught us all the latest psychological techniques: visualization, association, etc. It was great." "That's great! And what was the name of the clinic?" Fred went blank. He thought and thought, but couldn't remember. Then a smile broke across his face and he
asked, "What do you call that flower with the long stem and thorns?"
"You mean a rose?"
"Yes, that's it!" He turned to his wife, "Rose, what was the name of
that memory clinic?"
