TEACHER AND TED

Teacher: History is a very interesting subject. It tells you about what had happened in the past.
TED: Please teacher, I don't think I want to study history.
TED: Why?
Student: There is no future in it.


Teacher: Ted, if your father has $10 and you ask him for $6, how much would your father still have?
Ted: $10.
Teacher: You don't know maths.
Ted: You don't know my father!


Father: Why did you fail your mathematics test?
Son: On Monday, teacher said 3+5=8
Father: So?
Son: On Tuesday, she said 4+4=8 And on Wednesday, she said 6+2=8.
If she can't make up her mind, how do I know the right answer?
