Back in the day, Mark Harmon was rather dapper student attending Harvard High School. After graduating in 1970, he then headed off to UCLA, where he would eventually become quarterback of the football team.
After he hung up his cleats, he turned to acting, and his first role was on the popular primetime soap 'Flamingo Road.' And who else remembers seeing Harmon on the cover of People when he had his brief moment of glory as the Sexiest Man Alive? We can't really imagine Gibbs caring about magazine covers, but for a young Mr. Harmon it was a career-defining highlight. That is, until he appeared in a guest-starring role in 'JAG' that would eventually lead to starring in the CBS hit 'NCIS.'
Check out Harmon's humble beginnings after the jump.
Looking pretty good, right?
