Einstein meets Homer Simpson
Einstein: So Mr. Simpson, what makes you say the universe is shaped like a doughnut and is expanding?
Homer: Mmmm, expanding doughnut.
Einstein: Do you think the expansion is due to dark matter and dark energy?
Homer: Dark matter? Oh, you mean chocolate. There's lots of energy in chocolate.
Einstein: Hmmm, chocolate?
Homer: Mmmm, chocolate.
