In a philosopy class, a professor discusses about the existence of God...
Professor: Who can prove to me that God really exist, raise your hand and explain!
No one dared to raise a hand...
Then suddenly, a student stood up...
Student: I believe God exist, sir!
Professor: Really, Have you already talk to to Him?
Student: Uhmmm.... No.
Professor: Can you see Him?
Student: No!
Professor: Now! To see is to believe! Then how can you prove that God really exist?
Student: Sir, can I ask something first?
Professor: Uhmm.... Okey! Go on.
Student: Can you touch your brain?
Professor: No.
Student: Can you see your brain?
Professor: Definitely, No!
Student: (To the whole class) Classmates! Let us go home! Professor got no brain!
(^_^? Nice one! LOL!
