What? (goes with the Thing.1)

What makes you tick,
What makes you scream,
When things aren't always what they seem?
What makes you jump,
What makes you cry,

When someone says to go bedy-bye?
What makes you jolt,
What makes you run,
When I'm just having fun?

What makes you shake,
What makes twitch,
What is it about me that makes you itch?

Tick, scream, jump, and cry,
Until you go bedy-bye.
Jolt, run, shake, and twitch,
Because I think you have a itch.
