"There is no God"

A Lutheran, who was a senior at the University was getting rather tired of professors who felt they had to teach atheism. His professor started the class by saying the following: "Students, is there anyone here who can see God? If so, raise your hand. If there is anyone here who can hear God, raise your hand. If there is anyone who can smell God, raise your hand." After a short pause, with no response from the students, he concluded, "Since no one can see, smell or hear God, there is no God." The student then raised his hand and  asked to address the class. The Student approached the class and asked, "Students, can anyone here see the professor's brain? No response from the class. Can anyone here hear the professor's brain? Again no response. Can anyone here smell the professor's brain?" After a short pause, he concluded, "Since no one can see, hear or smell the professor's brain, I conclude that he has no brain!
