Big Bang Theory Quote
Sheldon: I must say, Amy, I was very impressed to see that Bernadette got her Ph.D.
Amy: It's indeed admirable. Although it is microbiology.
Sheldon: Your doctorate is in neurobiology. I fail to see the distinction.
Amy: I'll make it simple for you. I study the brain, the organ responsible for Beethoven's "Fifth Symphony." Bernadette studies yeast, the organism responsible for Michelob Light.
