Surprise Doctor is a Circlejerk that had originated from mid 2019 Dogelore, it is quite unknown how or when it started gaining popularity on the server. Or how the general concept of "Surprise Doctor" even started.
The Original Footage of "Surprise Doctor" comes from a Spanish YouTube Channel, titled "Señor Wooly", owned by a gringo Spanish teacher that creates educational Spanish songs and videos for middle school and high school. His creations include Billy la Bufanda, Guapo, and ¿Puedo ir al baño?, among many others.
The music video with the original footage of "Surprise Doctor" is titled "Ya está muerto", it is about the main character, The Surprise Doctor trying his best to revive a patient by putting a heart in his backpack. And him ultimately failing with that goal, in the music video The Doctor, instead of saying "Surprise Doctor Always Surprises" says "There is Another Way.".
This Circlejerk has been appearing relatively often in Dogelore, it is still remembered by many Veterans of the Server from The Pre Civil War Period.
