Furnace Filters and Ice Cubes

“Hey Daddy. What have you been doing today?”

“I just finished changing the furnace filters. It’s going to get cold and we need to turn on the heat. I replaced five filters,” he said.

Me: “Five filters? Why so many?” Their house is less than 3000 square feet.

“Well, there was the one on the furnace and one on each cold-air return.” I’m rolling my eyes.

“It was a hot job. I poured a glass of Coke. I put some ice cubes in it and drank it. Then I rinsed off the ice cubes and put them back in the freezer.”

Me: “Don’t save the ice cubes. They have germs on them. Just throw them in the drain. You have plenty of ice.”

Him: “I like to use the ice cubes again.”
