The Yorkshireman's wedding anniversary

Bob and Joan had been married for forty years so to celebrate their anniversary decided to take a trip into town.

As they walked passed a swanky restaurant, Joan turned to Bob and said
"Ooh Bob, Can you smell that? It smells lovely"
"You know something Joan? You're right. Seeing as how it's your anniversary, we'll walk passed it on our way back so that you can smell it again"
