Sheldon isn't looking forward to the faculty mixer where he will meet his new boss, Dr. Eric Gablehauser, who Sheldon doesn't respect. Due to an inappropriate comment to Gablehauser, Sheldon promptly gets fired. Sheldon has no interest in getting his job back. With his new found free time, Sheldon works on a series of rather meaningless experiments at home, which drive Leonard and Penny crazy. Feeling at the end of his rope in dealing with a crazed Sheldon, Leonard calls in the one person who he thinks can get Sheldon out of his funk: his mother. Mary Cooper, a religious southerner, deals with her son in her own special way, which may have a side benefit to herself. Written by

Yeah, it really takes the pressure off.
In the opening scroll of the time line when it gets to 91,000 there is a mistake the dates read 93,000BC 92,000BC 91,0009C 90,000BC for some reason 91,000 is a 9c not a BC. See more
