Sam: Mommy, is today April first?
Me: Yes sir...it's April Fools Day! We're going to have to think of a good trick to play on Daddy.
Sam: (runs into kitchen for a moment and runs back out laughing maniacally) APRIL FOOLS!!!
Me: Sam, what did you do?
Sam: I'm not telling.
Me: Sam, WHAT DID YOU DO? You better tell me.
Sam: I hid the salt shaker and then said, "April Fools," to you! (laughing so hard I thought he was going to fall over)
I love that kid.
