Big Bang Theory Quote
Sheldon: (discussing why Leonard lied to Penny to get out of hearing her sing) Then I suppose you could have agreed to go.
Leonard: And, what would I have said afterwards?
Sheldon: I would suggest something to the effect of: "Singing is neither an appropriate vocation, nor avocation for you, and if you disagree, I'd recommend you have a CAT scan to look a tumor pressing on the cognitive processing centers of your brain!"
