There was a student who was sent by a teacher to take a quiz. Entering the room, the judges asked:
- Do you know who invented the rabies vaccine?
The embarrassed student answered:
- Ephesus!
The jury asked:
- Is there a ghost in this world?
The student said:
- Scientists are studying!
The jury gave him the class. Arriving at the class, the teacher wanted to try to see how she would test and ask:
- What did Stephen invent?
The student who thought she pretended to try and replied:
- Vaccination against rabies!
The teacher was furious because her students were too bad and asked:
- Are you crazy?
He thought that the teacher asked him to repeat the sentence like the previous sentence.
- Ladies, scientists are studying.
The teacher said:
- Oh, so you're an alien.
