Every one of those old songs like "What's My Age Again?" and "All the Small Things" is like a tattoo or a scrapbook or an old photograph. There are just songs that define certain moments in your life. Everyone has a song that got them through a bad breakup or they put on and it made them feel like they wanted to go out and kick the world's ass with their friends on a weekend. Those songs still feel like that to me.

Being a producer is a very different experience than writing my own songs.

He [Patrick Stump] is been a friend of ours for a long time, and when we were talking about working with different producers and songwriters for the record, Patrick's name came up. We were excited to work with him - he's a very gifted lyricist and songwriter, and a really cool guy and it was a pleasure to work with him in the studio.

I liked seventeen-year-old me, I was happy when I was seventeen. I was this troubled goth kid that wore eyeliner and make-up to school and listened to punk-rock music and I loved my friends and I started to make music - I like seventeen-year-old me.

Screw them. Yeah. But not literally. I'm not advocating promiscuity.

I don't think any of us felt like, "Oh, we need to put joke songs on the record." If we found something funny, we would record it, and if we wanted to, we'd put it on the record. It's not really something we spent too much time agonizing over.

I think when people are jumping on top of each other's ideas, it elevates it a lot more than me going into the studio and working on something all by myself for a while.
