I thought this joke was pretty funny:
Moses dies and goes to heaven. G~d greets
him at the Pearly Gates.
"Are you hungry, Moses?" asks G~d.
"I could eat," Moses replies. So G~d opens a
can of tuna and reaches for a chunk of rye bread
and they share it. While partaking of this humble
meal, Moses looks down into Hell and sees the
inhabitants devouring huge steaks, pheasants,
pastries and wines. Curious but deeply trusting,
he remains quiet.
The next day G~d again invites Moses to join him
for a meal. Again it's tuna and rye bread. And,
again, Moses can see those denizens of Hell
enjoying salmon, champagne, lamb, chopped
chicken liver, truffles, and chocolates. Still he
says nothing.
The following day, mealtime arrives and another
can of tuna is opened.
He can't contain himself any longer. Meekly, he
says: "G~d, I am grateful to be here in heaven with
You as a reward for the pious, obedient life I led.
But here in heaven all I get to eat is tuna and a
piece of rye bread, and in that 'other place' they
all eat like emperors and kings! I just don't
understand."
God sighs. "Let's be honest," He says. "For just
two people, does it pay to cook?"
