Episode complete credited cast:


Leonard's mother has come for a visit. While Leonard wants to avoid her at all cost, Penny wants truly to bond with her despite the less than happy relationship Leonard has with her. So it's good timing for Leonard when Raj mentions that there is a special screening of The Avengers (2012) that he wants them all to go to. While Leonard and Howard are up for the evening out to the cinema, Sheldon doesn't want them to go without him, he who promised Amy he would go shopping with her at that time. When Leonard tells him that he can still go shopping with Amy and that they will save him a spot in line, Sheldon balks at the notion, not believing in "cutsies", that is until they mention that people nowadays are hired to do a number of unusual things, such as stand in line for others. Who Sheldon hires is Stuart, but not quite in the way they all had in mind. Regardless, Stuart relishes what looks to be his newfound wealth from these "person for hire" type tasks, while Sheldon still will not ... Written by Huggo

Crazy Credits


I'm thirteen years old, jammed in the backseat of a Chevy Impala. My uncle is driving. My aunt is in the passenger seat. My parents are in the back with me. The four adults are talking about where they ate last night. This then leads to what they ate, then to the quality of the food, then to queries about other restaurants they may or may not have eaten in. I remember thinking that when I grew up I would never be that boring, that shallow.

Fifty years later. I'm driving my car. (I paid retail for it, so I won't mention the manufacturer.) There are three other adults in the car as well. The conversation is about food. Where we ate, what we ate, how was it, and have we ever eaten at such and such restaurant. As the discussion goes on around me, I can't help thinking that I have betrayed my teenage oath. I've become the banal grownup I once decried. Anxious to regain my self-respect, I abruptly switch the topic to something more consequential. I choose the threat of antibiotic-resistant staph infections. My companions are startled. One asks what that has to do with polenta. I can't figure out a way to explain my long ago, silent vow so I angrily exclaim, "Everything!"

The rest of the drive to the restaurant happens in silence. See more »

Another sh**** episode.
6 May 2016 | by (Georgia, United States) – See all my reviews

There were a few funny spots early on but by the time the episode ended, it was at an overall loss for me. *Spoilers*

Penny was in a position to tell off Leonard's mother - which the woman greatly deserves and I would love to see - but the writers allowed the mother 'the win' in the discussion. Awwww, she wasn't invited or told about their wedding. Poor baby.

Of course the perfect Penny answer is, "What? Why would Leonard want you there? All you ever do is insult him!"

I admit that Penny did reply with "Would you have come if we'd invited you (to the wedding)?" To which the mother said, "No." But she (the mother) wanted to be invited.

You know, as a world-renowned psychologist, don't you know that relationships go both ways? If you don't like it, change. But right, it's not HER fault! Why should she change?

And the whole line cutting thing - that was pathetic. The guy cuts, gets totally away with it and then a woman accuses Sheldon? That whole scene just made me angry so any positive aspects from the little touch of humor, earlier on, was squashed.

Finally, Penny the 3rd sales rep in her company? Huh?! This is a character that could barely count to 100. How???

I don't know why I even bother watching this show anymore, unless it's simply because there is literally nothing better on.
