(scene opens at crowded breakfast table)

Beta: Mom! Mom! Mom!
Me: (shuffles out of kitchen, clutching coffee)
Beta: I got a question for you!
Gamma: (giggles conspiratorially)
Me: Hit me.
Beta: (smugly) What came first? The chicken or the egg?
Me: (sips coffee) The egg.
Beta: (not expecting an answer) How do you figure?
Me: Dinosaurs laid eggs. Birds evolved from dinosaurs. Chickens are birds. (sips coffee)
Gamma: (changes the direction of her laughter)
Beta: Wow, mom. Way to ruin a good riddle.
Me: I live to serve. (shuffles back into the kitchen)
