It tastes stale!
The two people in the dialogue below want to fix pork chops for dinner, but they later find out that the meat has gone bad....
Wayne: What are we going to eat for dinner?
Lilia: I'm going to fix some pork chops.
Wayne: I'm afraid the meat is rotten.
Lilia: That's strange! I just bought it the day before yesterday.
Wayne: Well, I forgot to put it in the refrigerator.
Lilia: Good for you! Now what should we eat?
Wayne: Why don't we eat out?
Lilia: Again? Weren't you just complaining that it's too expensive to eat out?
Wayne: Not when you're hungry.
