In a Simpsons episode of season 25 the dialoge
Monsarno Rep: Say hello to our chief scientist. Everyone: Augh! Sideshow Bob! Sideshow Bob: Dr. Sideshow Bob. Homer: Real doctor or PhD? Sideshow Bob: PhD.
takes place. In my country there is only a doctor and I thought a PhD would be exactly that in Anglo-Saxon countries. I would like to know is there a difference in the USA between a PhD and a doctor? Especially: What did they mean in the dialogue?
Edit: In hindsight this may be a duplicate, but originally it wasn't because I did not know that the "doctor" of the dialogue was about a medical doctor.
It's not the difference between "doctor" and "PhD". It's the difference between "real doctor" and "PhD".
"Real doctor"=someone who performs surgery, prescribes medication, etc.
"PhD"=Doctor of Philosophy
The joke is PhD's aren't "real" doctors. When someone says "I need a doctor", they aren't talking about needing an expert in the jackets of 1860s Chicago or Teichmueller spaces. They need someone to help with their medical ailment.
