When I was about eight years old I watched my grandfather sit down at the breakfast table with a bowl of cereal, a jug of milk and a box of orange juice, pour himself a glass of milk and then pour the OJ over the cereal. I didn't laugh - you did _not_ laugh at the old man - but then he just... stared at what he'd done for a second, poured the OJ out of the cereal into a different glass, poured the glass of milk into the OJ-infused cereal and ate his breakfast without a word.
