And then they realised they were no longer little Fall Out Boys. They were little Fall Out Men.

Pete Wentz announces the succesful launch of the Fall Out Boy: All Growed Up franchise:

He said: ''When we got on stage in Chicago, it was crazy. It was a rush, because we honestly didn't think people would care, and that's the truth. But it felt like we didn't miss a beat.

''It's so early in the process and things are happening so much faster than we thought; the first time you do things, there's no instruction book.

''It's not like 'Oh, OK, you shouldn't act like an idiot.' We're all more appreciative and we've all grown up a bit. It's cool to do Fall Out Boy as Fall Out Men.''

They honestly didn't think people would care, although they'd booked dates in three continents just in case.
