Quotes
(Sheldon sneezes)

Amy: You getting sick?

Sheldon: No, just allergic to people who get Nobel Prizes for no good reason

Amy: Sheldon, is it possible your foul mood, or, to use the clinical term, bitchiness...is because your mother isn't making you a priority?

Sheldon: No, or, to use the clinical term, na-ah.

Sheldon: I've got a treat for us tomorrow, Mom. I’m taking you to see Saul Perlmutter give a lecture about his Nobel Prize-winning work in cosmology. And the best part is, at the afterward, I've worked up a couple of Qs that will stump his sorry A.

Mrs. Cooper: I don't know, Shelly. I thought we could do a little sightseeing.

Sheldon: What sight is better than your little boy embarrassing a Nobel laureate?

Mrs. Cooper: I am still going out with your friends.

Sheldon: But I apologized. And that was hard for me since I didn't do anything wrong.

Mrs. Cooper: Shelly, I hung out with you in enough dusty lecture halls while you were growing up. I wanna go sightseeing. So why don't you have some pancakes, get dressed, and come with us.

(Sheldon enters, soaking wet while holding a tissue)

Sheldon: I need a tissue, this one got wet.

Mrs. Cooper: So Shelly what's up with you and your friend Amy, if you don't mind a mother prying a bit.

Sheldon: Well, there's actually big news on the Amy front. She's been studying, the neurobiology of addiction in lower animals, she is "this" close to getting a hooked on.

Mrs. Cooper: (to Leonard) You have any idea what's going on with those two?'' '' Leonard: Mm, it's kind of like the, and maybe there's something there, maybe there isn't, we'll probably never know. But, sometimes it's fun creeping yourself out thinking about it.

(the group, minus Sheldon, is visiting a church with Mrs. Cooper)

Raj: Hey, look. (shows Howard a cross with Jesus on it)

Raj: None of our look like that.

Howard: Yeah, that was the last Jews to ever do sit ups. And look where it got him.

Critics
"I didn't think it was very entertaining but Sheldon's refusal to change did feel believable. For someone who already thinks he is better than everyone else I can buy that he doesn't see the need to grow up emotionally. All he knows is that he was happy when someone was taking care of him and making him feel special. Why should that ever end?" The TV Critic's Review

Trivia

 * When Sheldon once again states he wants his mother with him to see Saul Perlmutter give a lecture about his Nobel Prize-winning work in cosmology (i.e., the discovery of the accelerating expansion of the Universe through observations of distant supernovae), the Einstein Field Equations, $$R_{\mu \nu} -\frac{1}{2}R\,g_{\mu \nu} + \Lambda\,g_{\mu \nu} = {8 \pi G \over c^4} T_{\mu \nu}$$, are visible on the kitchen in tensor notation, along with the cosmological constant expressed in terms of the vacuum energy density (Λ = 8$$\pi$$ρvac), the value for the equation of state parameter corresponding to the vacuum as a cosmological energy source (w = -1), and a crude estimate for the density parameter in baryons (ΩB = 0.05, 5% atoms).
 * In reference to Perlmutter, Sheldon says he is to people who get Nobel Prizes for no good reason and that he made more accurate diagrams of the expansion of the early universe on the  wall with the contents of his . Saul Perlmutter is mentioned again in "The Speckerman Recurrence" as Sheldon watches the Nobel Prize acceptance ceremony streaming live from . Therein, he asserts Perlmutter stole Einstein's cosmological constant.
 * On the other hand, Sheldon considers Nobel Prize winner-experimental astrophysicist George Smoot "one of the great minds of our time" and cites "his work in black body form and anisotropy of the cosmic microwave background radiation cemented our understanding of the origin of the universe."
 * In the first episode containing "Soft Kitty" ("The Pancake Batter Anomaly"), Sheldon tells Penny to rub the in counter-clockwise direction, otherwise his chest hair mats. However, in this episode, Sheldon's mother does not rub the Vicks Vaporub on Sheldon's chest in a counter-clockwise direction, but Sheldon does not correct his mother.
 * Mary Cooper is very, calling Japanese scripts (Kanji and Kana) "" letters, "Indians", and, as a , refers to s as " rattlers".
 * Mary confirms that Sheldon was tested for as a child and the doctor said he was fine. However, she does regret not taking him to a follow-up  in.
 * Mary and Sheldon imply that due to her cooking (she cooks everything with ), Sheldon's father died at 50 from complications related to.
 * Amy has an experiment where she is close to getting a hooked on.
 * When Penny hints to Leonard that her brother was "kind of a chemist" in "The Pirate Solution". He was actually a cooker and she asks  for him to stop her brother making it, but with no cops.
 * Sheldon wants to convert the elevator shaft into a so he can launch a strike on.
 * In several episodes, Sheldon is shown to follow a rule: offering a hot beverage to the friends when they are upset. This episode reveals this is because his mother taught him to do so.
 * For the first time in the series, Mary Cooper is seen to be visiting Pasadena, California, for a reason other than being called by one of Sheldon's friends to come to Pasadena to help them handle a Sheldon situation/problem. The reason for her visit to California in this episode is that she is visiting for the weekend before boarding a "Born Again Boat Ride").
