Neil Patrick Harris Then
Although he played many roles during his career, Neil Patrick Harris will always be recognized from How I Met Your Mother. However, some 90’s kids may also remember him for his role in Doogie Howser, M.D.
Harris played a genius kid who became a surgeon at the age of 14! Time flies by because Little Doogie is all grown up now. He continued acting throughout the ’90s but he got his iconic role as Barney Stinson in 2005.
