Memory Clinic

A husband and his wife along with their friendly neigbours were enjoying a friendly conversation when one of the men asked the other, "David, how was the memory clinic you went to last month?"

"Outstanding," David replied. "They taught us all the latest psychological techniques; visualization, association... it made a big difference for me."

"That's great! What was the name of that clinic?"

David 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?"

"Do you mean a rose?"

"Yes, that's it!" He turned to his wife, "Rose, what was the name of that clinic?"
