Can you guess who is this??
It's everyone's favorite funny man and lovable brother-in-law Alan, aka Zach Galifianakis in his senior year (1988) at Wilkes Central Senior High School, Wilkesboro, NC. Now, 41, Zach attended North Carolina State University after graduating from High School.
It looks like Zach was in full-on 80's mode during his teen years, happily rocking his denim button-up and warm smile. Who would've known this normal looking teen would transform into our favorite Hangover star and comedian.
