Episode complete credited cast:


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. Written by Huggo

Crazy Credits

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 »

A bit mellow compared to the others...
11 May 2010 | by (unknown) – See all my reviews

I've been repeatedly watching the series episodes over and over. You can say I'm a big fan of the series. But this episode was, in my opinion a bit mellow compared to the other episodes. The show started with Raj sneezing and Sheldon usual germaphobe attitude. Sheldon mentioned his lady friend is coming over and staying at their house for a few days. Turns out Leonard's a big fan of this lady friend, Dr. Elizabeth Plimpton.

As the episode progresses we come to realize that Elizabeth is a very promiscuous woman. After a night with Leonard she moved on to Raj and Howard, whose fortunate timing was invited to a threesome. And Leonard's arrival turned into an invitation to a foursome.

Well, there are some, and I meant little, funny moments. I don't know why but all the actors acting seemed a bit weird. Like there was a fight off-screen and it was not resolve or something. Oh well, I still love the show and as always "GO TEAM SHELDON"
