Blink-182's Mark Hoppus Recalls Roof Diving, On 'When I Was 17'

'It's a miracle that we're still here,' he says on latest episode, airing Saturday at 11 a.m. ET/PT on MTV.

On the next episode of "When I Was 17," Mark Hoppus, bassist for [artist id="783"]blink-182[/artist] and host of Fuse's "Hoppus on Music," sheds light on what his life was like before he was asking "What's my age again?"

Surprisingly (except not at all), he was as out of control back then as he is now, as he reveals on the episode, airing Saturday at 11 a.m. ET/PT.

"We were really smart as high-schoolers. We had a friend, his name was Dave, he had a two-story house, and in the backyard of his house was a pool. And his parents would leave for days at a time, so of course, Dave's a responsible guy, he wouldn't let anything bad happen. So we would jump off a second-story roof into the pool," admitted Hoppus, who just finished up on the Honda Civic Tour alongside My Chemical Romance. "We called it Acapulco cliff diving."

"It was definitely high enough so that if you jumped in, you had to turn your body as soon as possible so that you didn't eat your knees," he added.

While at first it started off safe — well, sort of — Acapulco cliff diving soon became more and more competitive as time went on.

"At first I think it was cannonballs and feet first, and then we'd one-up each other and by the end, people were doing flips. I definitely dove headfirst into this pool. It's a miracle that we're still here."

And a miracle it is, Mark. Because we can't imagine what life would have been like without some Blink-182.
