We do not use only ten percent of our brain

Gaston is renting out his brain.

Ninety percent of it. Great location. Barely used.

Gaston: We only use ten percent! The rest is free real estate!

Pip: Who would even rent ninety percent of you?

Gaston's wife: We need a holiday home. Quiet. Empty.

The Wolf: A neurologist at Johns Hopkins calls the ten percent idea so wrong it is almost laughable. It's a myth.

Gaston: So my brain is... fully booked?

Pip: Fully booked. Mostly recipes.

Gaston: Wait! I have something quiet. And very empty.

Gaston's wife: Quiet. Empty. Perfect.
