My Stupid Mouth is probably the most emotionally autobiographical song that I've ever written. Every year before school started I said, This is gonna be the year that I'm gonna go to school and be quiet. And I'm gonna be very sort of tactful, and speak when spoken to. And I could never do it. Twenty minutes into class I just ruined it. I'm never speaking up again, starting now.
People really grabbed onto that one because I think everybody has had that experience where they just—they sort of go, You know what, I'm just not talking anymore.
