Neil Patrick Harris and Freddie Prinze Jr.
I was surprised that Doogie Howser actually attended a real high school while playing the role that we will forever remember. Neil Patrick Harris attended La Cueva High School in Albuquerque, New Mexico, along with Freddie Prinze Jr. And just a few miles away, at Saint Pius X High School in Albuquerque, was future Modern Family star Jesse Tyler Ferguson.
