Recap

Leonard and Sheldon are attending a party at the university to the new department head, Dr. Gablehauser. Sheldon feels Gablehauser is not worthy of his respect and, unwilling to schmooze his superior, tells his new boss that and is promptly fired.

With Sheldon no longer working, he is spending his time trying to perfect scrambled eggs. When Penny calls to see if the guys need anything from the supermarket, Sheldon tags along to buy more eggs for his experiments. Back at the apartment, Sheldon has moved on to his next grand idea: luminous fish night lights.

Concerned at his friend's behavior, Leonard calls Sheldon's mother. When Mary Cooper arrives, Sheldon has got a loom and has taken to weaving panchos. Annoyed that Leonard called his mother, Sheldon retreats to his room. Meanwhile, Mary cooks dinner for the gang as they get to know her and find out more about Sheldon's childhood.

When Mary's patience with Sheldon has been tested, she tells him she will take him to the university to solve this and she won't have any argument. While Sheldon reluctantly apologizes to his boss, Mary finds herself flirting with Dr. Gablehauser. Later that day, Mary puts Sheldon to bed and tells him how proud she is that he apologized to his boss.

I don't find what Sheldon did when he was off work was that odd. He did make the fish glow in thr dark and his ponchos were pretty good. He does have a creative mind and is always thinking of new things, once again, Penny was nasty to him as well. He was probably right about the viatmins. About the tampons, he was just trying to help her. This is something that should be dicussed more opnely anyways. Billions of women go through that stuff every day.

I love the observation Sheldon makes to Penny about how many tampons she purchase a month. Truly hilarious! Even funnier is how he fails to grasp "his advice" is unwanted...:D
