My mother and I went to the store to buy groceries. The cashier starts punching the cottage cheese, stops, thinks and starts looking for the expiration date. She found it, looked at it and with a clear conscience put the cottage cheese in our bag. Mom:
– Well, are we going to live? Cashier (with an imperturbably serious face):
– Until the twenty-fourth!
