A tzadik died and went directy to Gan Eden. For dinner the first night with Hashem, they both had a tuna sandwich and soda. The tzadik peered down to Gahenim and saw the group there were dining on chicken, roasted potatoes, and a salad, with a lucious dessert. The second night the tzadik and Hashem had a tuna sandwich and soda, while in Gahenim they had a delicious dinner. The meals were repeated the third night, and the tzadik asked Hashem, “Why do we have only tuna in Gan Eden and the ones in Gahenim have a great dinner? Hashem answered, “Frankly, it doesn’t pay to cook for two”.
