No Foolin'

Pulling a prank to a nearly-five-year-old means this:

Weston: "Mom! There's a spider on your head!"

Me: "What? A spider on my head" as I finger my hair in mock fear.

Weston: "Do you know what day is it?" (Not a typo...he said "is it")

Me: "No, what day is it?"

Weston: "I'm not telling!"

Good one, West! You got me!
