Two senior couples are walking along, wives in front, husbands in
back.  Herb says to Sam, "Gee, we went to a new restaurant last night
and had the best meal ever.  Good prices too."

Sam says, "Well, we like to eat out too.  What was the name of the
restaurant?"

Herb says, "You'll going to have to help me out here a little.  What's
the name of that pretty flower, smells sweet, grows on a thorny bush?"
Sam says, "How about rose?"

"Yes, yes,  that's it!" cries Herb, then calls ahead to his wife. 
"Rose.  Hey, Rose. What was the name of the restaurant we ate at last
night?"
