Two couples, both in their 70's were chatting. One man said to the other "Hey, Bob, how did that memory therapy you took work out?"
Bob said "Oh, it was great. They taught us all kinds of things, like using similar words to help us remember things. Overall, my memory has really improved."
The first man says "That sounds great. I should go there. Where is it?"
Bob replies "Oh, now just a second...I can't think of the name of the street...just give me a second. What do you call that flower, it's usually red, with thorns on it?"
His friend said "A rose?"
Bob said "That's it!" and turned to his wife and asked "Rose, what was the street that the memory clinic was on?"
