A gentlemen has been going to his doctor because of his failing memory. The doctor gives him some medication.

A couple of weeks later, he is having dinner with some friends. He tells them about the medication and that it seems to be improving his memory.

One friend asks what is the name of the medication.

He replies "What is the name of that flower that smells great and has thorns on it?"

"A Rose ," repeats one of his friends.

And the man turns to his wife and says" Rose, what's the name of that medication I'm taking?"
