verse 1 Jack, from school He listened to Bowie People thought he was cool He used to live for the thrill Skating around up in the Hollywood Hills Pre-Chorus But no one knows He's talking it up That it's all for show He's boring as fuck 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 Palisade Pre-Chorus But no one knows That it's all for show You're Ms. Know-It-All You're 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 have known I tried to change with love to say hello Please, don't hang up Afraid of what I'd say Hello, hello, hello I'm Mr. Know-It-All 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
