Funny things that I heard during phy...

during physic revision class, the teacher suddenly asked what's the difference between Grammy and Oscar. And continued to ask who is "the Oscar guy". Then, one student said, "my great-grandfather!"

Then, the teacher asked the class about one question related to light. The same guy asked if he's going to ask that in the exam. The teacher asked him back, why he (the student) asked that. The student answered,"because u always give easy questions and this question is hard!"

Taking about Mexican waves (kallang waves as we refer to in s'pore)...

Student: "why is it called Mexican waves?"
Teacher: "because the first wave, the very first wave, was generated in Mexico!" (who would believe that!)
Teacher: " u ask a question and as the instructor, I'll give u an answer. But whether the answer is correct or not, it's another matter!"
