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

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

"Who was the instructor?"  asked the neighbor.

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

"A rose?"  offered the neighbor.

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