Some people may think this joke is only funny to senior citizens. I
think not. My parents heard it at an elder hostel in New Mexico this summer.

Seems that this old couple are having trouble remembering things, so
they sign up for a memory course. The course is wonderful; they come
home and tell all their relatives, friends, and neighbors about it.
Some months later, a neighbor approaches the man as he tends the
garden.

Neighbor: Say, Ed, what was the name of the instructor of that memory
course you liked so much?

Ed: Well, it was…hmmm…let me think a minute…

Whats the name of that flower, you know, the one that smells so
nice, but has thorns on the stems…?

Neighbor: You mean a rose?

Ed: Yeah, thats it…(shouting toward house) Hey, Rose, what was the
memory course instructors name?
