A medical Doctor is teaching, and everyone is around a corpse, ready for their first lesson. "Welcome, class. OK, since this is your first lesson, I have to tell you: The 2 most important things to be a good doctor are: *Dedication* and *Observation*." Doctor then proceeds to unveil the corpse, a big, fat woman who got shot in the head. "This is *Dedication*". The doctor proceeds to stick a finger up the fat lady's ass, then licks it. Everyone is disgusted. "I suggest you all do the same" One by one, the students stick a finger up the old, fat corpse, then lick it. Once they are all done, Doctor comes up and says: "The second one is *Observation*, I put my index finger in, but I licked my middle finger"
