An elderly couple went to dinner at the home of some friends, also elderly. After dinner, the wives went into the kitchen and the two men were talking. One said, "We went out to dinner last night at a really good restaurant. I'd highly recommend it."

The second man said, "What's the name of it?"

The first man thought and thought, then said, "What's the name of that flower you give to someone you love, the one that is usually red that has thorns?"

"Oh, you mean a rose?" said the second man.

"Yes, that's it," said the first man. Then he called to the kitchen, "Rose, what's the name of that restaurant we went to last night?"
