Immaturity has been bliss for the boys of Blink-182. The San Diego trio — singer-bassist Mark Hoppus, singer-guitarist Tom DeLonge and drummer Travis Barker — has crashed the hit parade with its near-perfect pop-punk anthem, "What's My Age Again?," in which a twenty-three-year-old idiot crank-calls his girlfriend's mom and chooses TV over sex. In this band's case, the line between art and life is pretty much nonexistent: The guys streak through Los Angeles in their video, indulge in obnoxious puns (album title: Enema of the State) and proudly proclaim their love of porn (album cover: adult-film star Janine). Hoppus, 29, was raised in the desert town of Ridgecrest, California ("If you ever end up there, you really pissed off God"), but has no plans to grow up anytime soon.

So you finished the Warped Tour?
Yeah. We're shooting our new video tomorrow. We're spoofing the Backstreet Boys and boy bands in general. We're gonna dress like 'em, try to dance. It's gonna be funny.

One of you needs bad facial hair.
I know. We're gonna stuff the front of our pants, too.

Do you secretly like any boy bands?
To be honest, I kind of like that Backstreet Boys Millennium song. I mean, you hear it and go, "Man, this is terrible," but then for the rest of the day, you're like [sings], "Tell me whyyy..."

When did you guys get together?
Eight years ago. My sister was going out with one of Tom's best friends. Tom had the shittiest job — he'd get up and load hundred-pound bags of concrete onto a truck, drive it to where they were building and unload it. I'd dropped out of college and was living at my parents'. Tom would go to work at five in the morning, and I wouldn't get up until noon. Tom would come by after work, and he'd have lifted fifty metric tons' worth of concrete, and I'd still be hanging out in my underwear, playing Nintendo.

What's the most immature thing you've done recently?
Uh, let's see. I was in line to use the restroom on a plane. This woman came out, and as I walked in, I said, "Oh, my God, it smells terrible in here!" The whole plane turned and looked at her. The bathroom didn't smell bad at all, but the lady totally took the rap for it.

Cruel. So do people expect you to be exhibitionists because of the video?
Yeah. The video's great; it's done incredible things for us. The only thing that sucks is, every time we do a show or something, people are like, "You guys gonna do it naked?" But I came up with a really good line: "Look, I got naked one time for a video — kind of like your mom."

Have you had lots of experience with public nudity?
Yeah. I just think there's nothing more awkward or stupid-looking than a naked guy, so we'd be on tour and I'd go into another band's dressing room totally naked and go, "Hey, you guys seen my towel?" So it wasn't that much of a stretch to run around naked in L.A.

So you're very comfortable with your body?
Yeah, I'm cool with that. I'm like, "You know what? I know I've got a disgusting body, but I think it's funny, so I'm gonna make people laugh at it."

Is there more nudity at your shows now?
Yeah. Now girls show us their boobs all the time. Granted, there are times we say, "Show us your boobs!" Actually, we always say, "If you guys wanna get naked, it's all right with us," 'cause "Show us your boobs" sounds a little sexist, you know? But even if we don't say anything, girls show us their boobs.

No naked guys, though?
Not so much in the audience, but we'll be doing signings and guys will come up and go, "I want you to sign my ass."

You need to draw the line there.
I mean, I got into this business to try to get chicks, and I'll do whatever it takes, but signing guys' asses is in the no zone.

Does it annoy you when people confuse you with Eve 6 and Matchbox 20?
[Laughs] That actually hasn't happened, but one time at the Warped Tour, this kid came up to me and said, "Can I have your autograph? I loved your set today." And I go, "But we haven't played yet." And he's like, "Aren't you Eminem?"
