If you grew up in the 70's or 80's, you probably learned grammar, math, and civic lessons from a cartoon series called, "Schoolhouse Rock."
Sadly, the creator of "Schoolhouse Rock" has died. 94-year-old Bob Dorough passed away Monday from natural causes at his home in Pennsylvania.
Take a trip down memory lane and watch some of these "Schoolhouse Rock" videos from back in the day.
