Big Bang Theory Quote
(Leonard's mother Beverly, a neuroscientist and psychoanalyst, is visiting)
Sheldon: Your mother is brilliant, analytical, insightful - and I'm betting she never hit you with a Bible because you wouldn't eat your Brussels sprouts.
Leonard: Sheldon, you don't give your mother enough credit. She's warm, she's loving, she doesn't glue electrodes to your head to measure your brain waves while potty training.
Sheldon: You were lucky! When I was a kid, if I wanted an EEG, I had to attach my *own* electrodes.
