A shocking surprise
A shocking surprise is when your dad pulls out a blender and sticks it up your butt while you're taking a nap. It sounds like a blender and your butt are having a party.
My dad did this to me on my birthday. I woke up with a sore butt and a sore brain.
My brother tried this on his dad during a football game. The whole team laughed so hard they lost the game.
My cousin did this to her dog while it was chasing a squirrel. The dog ran away screaming.
