If Leonard has a full-time job at the university heвЂ™s probably earning well now, but he would have spent years in a PhD program living off Ramen Noodles while everyone else went out into the real world in order to reach that point). Penny had assumed Leonard would come with her, not realising that he doesnвЂ™t do his job for money (Bernadette does, but she is in a rather more lucrative branch of science than experimental physics. Leonard and Penny, of course, havenвЂ™t discussed what they would do if this happened, despite the fact such a scenario is extremely likely given that academics usually have to go wherever the jobs are and actors generally have to travel a lot and sometimes have to relocate on a fairly long-term basis. Raj was clearly too busy imagining his future as a wrinkled but still flexible MadonnaвЂ™s toy boy to realise that writing a future in which Leonard and Penny have broken up in a very realistic scenario (their careers both took off and they drifted apart, with Penny living in London and Leonard a professor at Stanford) was a truly terrible idea.

(We were a bit disappointed that we didnвЂ™t get to hear them all, but we did get to hear that Amy has won a Nobel prize and has bought and shut down the comic book store in a desperate attempt to get Sheldon to pay attention to her, which Amy thinks is вЂnot the worst ideaвЂ™). He really should have realised that having everyone play themselves was bound to go wrong, especially when it emerges that the murderer came back in time from twenty years in the future to do the deed, meaning that he has written futures for all of them. Meanwhile, back home, Raj is making everyone play a murder mystery game in which Stuart has been murdered and one of them, in character as themselves, has done it. There is also a more serious point to be addressed in this episode, as the plot requires SheldonвЂ™s mother to do something she would normally be against, and Laurie Metcalf balances her performance perfectly, imbuing MaryвЂ™s admission that sheвЂ™s struggled with that issue and that sheвЂ™s вЂnot perfectвЂ™ with depth and sincerity, but not allowing it to slide into anything maudlin, finishing up with a perfectly delivered вЂthat manвЂ™s booty is.вЂ™ As always, the show is not overly mean-spirited to either party, a tricky thing to pull off where religion is concerned. вЂAn insult to her faith is always thoughtfulвЂ™ observes Howard wearily. Howard, for example, wants to be a good guest and bring pie and flowers, while Sheldon wants to give his mother вЂthe gift of knowledgeвЂ™ (specifically, a recent archaeological discovery that suggests there were no camels in the Middle East during the period covered by the Old Testament, contrary to the suggestion of an unspecified Biblical passage). That tradition continues here, as thereвЂ™s plenty more humour to be had out of Mary CooperвЂ™s religion and SheldonвЂ™s attitude towards it. SheldonвЂ™s motherвЂ™s views are in complete contrast to the gangвЂ™s (and she has been occasionally racist, sexist and other вЂ“ists in the past, partly due to the generation gap as much as anything else) but she is a kind, considerate and largely sensible character who seems to have dealt reasonably well with the difficult job that was raising Sheldon, a child who tried to achieve nuclear fission in his backyard. She is a fundamentalist Christian, her views the polar opposite to SheldonвЂ™s (who feels that there is no need for religion if we have science) and in every appearance, the show manages to walk a fine line as they mine this rich-looking seam for humour but avoid allowing the humour to get vicious or offensive to either scientists or Christians. The geekiness and intellect of the four guys are contrasted for comic effect with PennyвЂ™s social skills and common sense.SheldonвЂ™s mother has always been one of the best written and acted guest characters on the show. The show is primarily centered on five characters living in Pasadena, California: Leonard Hofstadter and Sheldon Cooper, both physicists at Caltech, who share an apartment Penny, a waitress and aspiring actress who later becomes a pharmaceutical representative and who lives across the hall and Leonard and SheldonвЂ™s similarly geeky and socially awkward friends and co-workers, aerospace engineer Howard Wolowitz and astrophysicist Raj Koothrappali.
