Two elderly couples are driving to a restaurant. The driver turns the guy sitting next to him and says: "What's the name of the place we're going?"
The second guy says: "Hmmm. What's that flower that's red on top and has thorns?"
The driver says: "A rose?"
The other guy says, "Yeah, that's it," and turns to his wife in the back seat: "Rose, do you remember the name of the place we're going?"
