An elderly couple were experiencing declining memories, so they decided to take a power memory class, where they teach one to remember things by association.

Later, the man was talking to a neighbor about how much the class helped him.

"Who was the Instructor?" the neighbor asked.

"Oh, let's see," pondered the man. "Umm...what's that flower, you know, the one that smells real nice but has those thorns...?"

"A rose?" offered the neighbor.

"Right," said the man. He then turned toward his house and shouted, "Hey, Rose, what's the name of the guy we took that memory class from?"
