I'm sitting at the dinner table with wifey and my three daughters, casually sipping my kit and bits stout, Idi Amin Scottish Ale, when the conversation turns to astronomy.
Daughter 2 says "Dad, did you know that in 2000 years there'll be no water left on Earth?"
Dad "No, why?"
Daughter 2 "Because the sun will get bigger and boil it all up."
Dad "Oh, well there'll still be water, but the Earth and all the water will be boiled up and melted into a big steamy ball."
Daughter 2 "Like Jupiter. Jupiter is a gas planet."
Daughter 1 "Dad, did you know Uranus is a gas planet."

2000 light beers from home.
