[Verse 1]
Jack from school
He listened to Bowie, people thought he was cool
He used to live for the thrill
Skiing around up in the Hollywood Hills

[Pre-Chorus 1]
But no one knows
He's talking it up
That it's all for show:
He's boring as fuck

[Chorus]
You're Mr. Know-It-All
She's staring at her phone
And even though you sit together
You feel so alone

It's such a tragedy
When people hardly speak
Try to live up to the person
You pretend to be

You're Mr. Know-It-All...
You're Mr. Know-It...
[Verse 2]
Jill liked art
She listened to Mozart, people thought she was smart
She used to quote Hemingway
Trippin' on acid in the Palisades

[Pre-Chorus 2]
But no one knows
That it's all for show

[Chorus]
You're Mrs. Know-It-All
He's staring at his phone
And even though you sit together
You feel so alone

It's such a tragedy
When people hardly speak
Try to live up to the person
You pretend to be

[Bridge]
You must've known I tried to change
Would love to say
Hello, hello, hello (Hello?)
Please, don't hang up
Afraid
Of what I'd say
Hello, hello, hello?
I'm Mr. Know-It-All

[Chorus 2]
I'm Mr. Know-It-All
Staring at my phone
And even though we sit together
I feel so alone

It's such a tragedy
We always used to speak
Try to live up to the person
I pretend to be

I'm Mr. Know-It...
