\Verse{$ | \mathbf{F} | $}
 
All around me are familiar faces

Worn out places, worn out faces

Bright and early for the daily races

Going nowhere, going nowhere

Their tears are filling up their glasses

No expression, no expression

Hide my head, I wanna drown my sorrow

No tomorrow, no tomorrow
 
 \Chorus{$\nabla \mathbf{F}$}

And I find it kind of funny

I find it kind of sad

The dreams in which I'm dying

Are the best I've ever had

I find it hard to tell you

I find it hard to take

When people run in circles, it's a very, very

Mad world, mad world
 
 \Verse{$\nabla \times \mathbf{F}$}
 
Children waiting for the day they feel good

Happy birthday, happy birthday

And I feel the way that every child should

Sit and listen, sit and listen

Went to school and I was very nervous

No one knew me, no one knew me

"Hello, teacher! Tell me, what's my lesson?"

Look right through me, look right through me

\Chorus{$\nabla \cdot \mathbf{N} $}

And I find it kind of funny

I find it kind of sad

The dreams in which I'm dying

Are the best I've ever had

I find it hard to tell you

I find it hard to take




When people run in circles, it's a very, very

Mad world, mad world

\Outro{$\nabla^2$}

Enlarging your world

Mad world
