An elderly couple suffering from deteriorating memory signed up for a power memory class to improve their memories. The power memory method taught them to remember things by associating these with familiar objects. After completing the 5-day course, the old man was discussing the merits of the course with a neighbor in his backyard.

The old man claimed, "Signing up for that power memory class was one of the best things I've ever done."

The neighbor asked, "So who was your instructor?"

"Well, lemme see," said the old man. "What do you, ahhh, call that flower that smells nice but, ummm, has those thorns..."

"A rose?" volunteered the neighbor.

"Yeah, right!" nodded the old man who then turned towards his house and yelled, "Hey, Rose, what was the name of the instructor in our power memory class?"
