Well, as you all probably know his full name is Zachary Walker Hanson, but he just uses Zachary or Zac for short. And he just celebrated his 14 birthday, I hope he had a nice day with his family! He celebrated it on 22nd of October and he was born in 1985.
He is the goofiest Hanson, well that's what I think.
Zac broke his nose when him and Tay were swinging rocks off of a see-saw. That was REALLL smart, NOT.
