Regardless of how many years removed you are from your school days, it's impossible to think back on your educational career without also recalling the teachers who most impacted it. Whether because they were inspirational or horrendously ill-suited for the job, some teachers leave an imprint that stays with you for a lifetime. And the same goes for the fictional teachers who populate the world of television.
