Sheldon's brilliant pen pal friend, renowned quantum cosmologist Dr. Elizabeth Plimpton, is being wooed by Cal Tech. Sheldon invites her to stay with him and Leonard while in Southern California. Sheldon feels protective of her because he feels she is in the same genius class as himself. Leonard is in awe of their temporary roommate. Dr. Plimpton, however, makes it obvious to Leonard that she is interested in him more than just as a fellow scientist. Leonard has a difficult time keeping his intimate encounter with Dr. Plimptom a secret. She doesn't seem to mind as she sets her sights a little more broadly than just Leonard.

CHUCK LORRE PRODUCTIONS, #286 In public bathrooms I will sometimes use the "children's urinal" in order to feel like a giant. If no one's around, I'm likely to sing along with Aretha Franklin's version of "You Make Me Feel Like a Natural Woman, but not the Carole King version. I've never understood why anyone would bother making a porn movie that lasts longer than ten minutes. I often pretend that the person standing next to me in an elevator is an unwitting carrier of a deadly airborne disease unleashed by terrorists who hate our freedom. This, of course, forces me to hold my breath until the doors open. Forty years ago I measured my penis with a wood ruler. The irony was lost on me. Sometimes sex just seems like a lot of work. There are mornings when, for no perceivable reason, I turn into a teenage girl and repeatedly change my outfit. I floss so that my dentist will be proud of me. Even when asked, I have never been able to "talk dirty" to a woman without feeling like a complete idiot. My one attempt at manscaping ended in bloodshed. See more
