I forget the time, but I remember seeing a video of Alex interrupting a concert to yell at a guy that was screaming at his girlfriend (he might've been hitting her, but I don't recall). He yells for a bit, and everyone's kind of lost in this awkward silence for a moment when Alex finishes with "Dude, this isn't Pokemon, you don't need to have so much rage!" The band then proceeds to finish the concert as though nothing happened.
Jack has a microphone stand with over a hundred bras hanging from it. So many, in fact, that they rotate which ones they bring on stage.
