Happy Birthday, Zack Merrick!

Today, Zack will be celebrating at his home in Hawaii, surfing and getting a tan. "I keep it low key, that's usually how I do it," he says.

Jack Barakat says he likes to do the opposite. "I do like to make some pretty crazy birthday parties, pretty extravagant," he says. "It's something that helps you stay young forever."

The two talk about past birthday memories; Barakat says he threw a massive month-long celebration while All Time Low was touring through Europe. Meanwhile, Merrick has usually been in Florida for his birthday.
