Nathan and Matthew Leone, Madina Lake's frontman and bassist, are eyeing a cowboy hat full of folded questions suspiciously. "We play this all the time, we call it Popcorn," says Nathan, his brow furrowed in anticipation. "This seriously broke up marriages!" The twins have every right to worry - over the next half hour they spill the beans on naked fighting and piss-drinking. Oh, and reveal possibly the worst tattoo known to humanity...

If you could choose a spectacular rock 'n' roll death for yourself, how would you go? Matthew: "Probably a waterslide accident, like a really sharp turn that just sprung me over the side. That would be incredible." Nathan: "Then at your funeral everyone would kinda have to laugh at it as well as be bummed." Matthew: "And I'd still be in my Speedo shorts. If that happens to me I want everyone to go to my funeral in Speedos."

What's the worst fight you've ever had? Matthew: "We'd just got into college and we were living in a dorm. The shower was across the hall from our room, so we'd just run over there naked with a towel, take a shower then run back. We got into this pretty big argument and then he went to take a shower so I went into the bathroom and I grabbed his towel and came back and locked the door. I kinda forgot about it, I was just watching TV, and then all of a sudden I hear him going, 'Open the door a*sho*e'. I made him pay a little bit so I waited, and he was whispering these horrible profanities through the door. When I let him in, he proceeded to beat the shit out of me for 20 minutes, naked. I couldn't fight back because I didn't want to touch anything." Nathan: "It'll be the last fight you ever have with a sibling if one of you is nude, because it's just so wrong in so many ways!"

What's the strangest thing you've ever put in your mouth? Nathan: "He drank piss." Matthew: "I did. We were on holiday with our friends and we were really hungover, so we ordered iced tea from room service. I was in the shower when it arrived, so they poured half of mine out and filled the rest of it with urine. I was so incredibly thirsty and dehydrated. You know when you're that thirsty for the first three sips you don't question anything? And then I threw up all over the place." Nathan: "He goes, 'Did some of you assholes put salt in this?'."

What's the most unusual offer you've ever had from a groupie? Nathan: "We were in Arkansas. I was standing by our merch area and this girl came up. Her and her friend were asking if I would go back and sleep at their mom's house and have sex with them. Fifteen-year-old girls! So I'm like, 'I'm flattered but that's awfully illegal, I'm not interested'. They're like, 'Don't worry my mom's totally cool with it'. One of the girls says, 'I'll take off all your clothes' and the mom says to her daughter, 'You can take all his clothes, I'll take the rest of him'. The mom and the daughter! Isn't that horrible?"

What's your earliest memory? Matthew: "Nathan and I tried to turn the bathroom in our house into a swimming pool, so we clogged up the sinks and turned the faucets on. I just remember getting spanked really hard for that."

What's the meanest trick you've ever played on each other? Nathan: "This friend of ours went to the doctor because he was having panic attacks. So we said, 'While you're there you might as well ask for some Viagra', because it's fun to have around. So he did and we just went around putting it in our friends' drinks. It's outrageously funny. We actually did it to another band's merch guy. He was like 'What the f*ck is wrong with my beer?' because it was foaming like crazy. He just drinks the entire thing, then he's selling merch to these kids all night like [mimes hiding an erection behind the table], 'What the f*ck?!'."

Where's the most inappropriate place you've ever thrown up? Matthew: "I threw up on Nathan's t**s! It was from eating that crap on that TV show." Nathan: "Yeah, it was on Fear Factor. After we got out of the trench they hosed us down like we were cattle and then put us in the SUV to warm up, nude, and gave us two buckets. So we're sitting there nude, barfing at each other. It was like a scene from Hell!"

Are you hiding any really bad tattoos? Nathan: "I absolutely am! I'll show you! Hold on, I don't know if I've recently trimmed my pubes enough." Matthew: "Look at it! In all it's glory! It's a f*cking wizard holding fire!" Nathan: "Every time we go on tour we have this contest to see who has the worst one. I win every time!" Matthew: "I have a frog on my ass giving the middle finger."

What would you do with a million dollars if you had to spend it in a day but you couldn't give it away? Matthew: "I would probably buy myself an island. I would just pimp it out. Nothing too overindulgent but I would definitely have a pool, hot tub, waterfall, go karts, hang gliders, a laser tag arena, paintball... You know, nothing too outrageous!"
