A couple, married for 40 years, were out sitting on a park bench watching the world go by and chatting about the secret to their happy marriage. This was part of their conversation.
Man: " Whenever I get mad at you, you never seem to get upset. How do you manage to control your temper?"
Woman: "I just go and clean the toilet."
Man: "How does that help?"
Woman: "I use your toothbrush."
