When these girls throw themselves at you, do you ever catch any of them? (all laugh) Caught a few bras from time to time. (laughs) YOU DID? YEAH. Yeah, but, harry, you once made a great catch, actually, when we were onstage and someone threw a bra. Just, like, he was in the middle of singing a solo, and then went--just went boom, just caught it out of the sky. It was wonderful. Good work.

To the point where there was actually, um, nipple marks on the--on the car. Wait. You mean, they took their shirt off and... Yeah. And their bra off, yeah. They all, like, run over to the car, and, like, took off their tops. Um... It was the first time it happened, really. It's what--it's what dreams are made of. We--we drove into the hotel and we were like, "where didthatcome from?" So your whole band, your whole phenomenon, is only two years old. I mean, are you used to it yet or do you still say, "how did this happen to me?" Um, no, it's amazing, and we can't believe, like, all the success and stuff that we've had so far. It's just been, like, a magic, wild ride, really. Who's available? Who's dating? Who's out there? I'M UP. (speaks indistinctly) YOU'RE AVAILABLE? I've got a girlfriend. I have a girlfriend. You have a girlfriend? You have a girlfriend, harry? I'M SINGLE. (Barbara) YOU'RE SINGLE. I'm single. I am. So we got three available and two are tied up, right? Mm-hmm.
