Bernadette, through a gift to Howard, indirectly gets Leonard and thus the guys to think about getting more exercise in their lives. All things considered, they decide to attend a fencing class led by Barry Kripke, largely so that they can become swashbucklers like their movie heroes without having to break too much of a sweat. Beyond learning the technical aspects of fencing, the guys try to place their own sensibilities on the proceedings, while Kripke himself decides to act upon some information he learns in the class. Meanwhile, Stuart asks Penny, Amy and Bernadette for advice on how to attract more female customers to the comic book store. Stuart may not fully comprehend what they, especially Penny, tell him, as partly demonstrated through a comment he makes to Amy. Written by Huggo

Title Reference: The title refers to the machine that Howard invents to make it look like he was exercising. See more »


The guys are wearing their fencing jackets incorrectly as the strap (croissard) that passes between their legs is too tight. If they made a lunge, it would be very painful. See more »


Leonard Hofstadter: Listen, I should warn you that maybe asking Amy out isn't a good idea.
Sheldon Cooper: Barry, a word?
Leonard Hofstadter: And now the crazy version of what I just said.
Sheldon Cooper: If you intend to pursue Amy, you leave me with no choice but to put a stop to it.
Barry Kripke: And how are you gonna do that?
Sheldon Cooper: By challenging you to a duel.
Barry Kripke: You've had one lesson. I'll destroy you.
Sheldon Cooper: That is why the duel will take place at high noon, three years from today. If you're worth your salt as an instructor, I should be ready by then. Yeah, and be warned. I'm going to ...

Crazy Credits


It seems to me that the biggest, most momentous choice of our lives is the one that none of us gets to make. I'm talking about the decision to be here, to be alive. Now before we digress into the choice of leaving this life, a subject best suited for handwritten notes left on the bed stand, let's investigate the initial premise. Simply put, we all arrive here screaming, crying and covered in goo, without prior consultation. Or so it appears. If in fact we were part of the decision to become cognizant, the memory of that process has been completely wiped from our consciousness. But what if it were retrievable? What if we could become aware of the primary decision to live, the fateful choice to participate in the world of time, energy and form? Wouldn't that improve our daily condition? No matter how difficult and confusing life was, we would always be clear on one thing, "I asked to be here. This is my choice." Of course, there's another option to consider. We are here against our will. The unending cycle of birth, life and death is a sentence. We are souls in prison. But that grim, Matrix-like scenario falls apart the minute you ask how hell on earth could possibly include gelato. See more »

TV Review: TBBT Season 9 Episode 5
9 November 2015 | by dvintihSee all my reviews

The Gist: Bernadette wants Howard to exercise, and the guys decide to join Barry Kripke's fencing club. Stuart seeks the ladies' advice to increase female footfall in his comic book store and Amy's life post break-up is moving faster than she expected.

Best scene: Just like naughty schoolchildren in absence of teacher, boys indulge in silly sword fight when Kripke isn't around.

How as we grow up, we become both more mature and more child-like: Sheldon is keen to learn fencing from his once arch enemy Barry, and still would kill him in 3 years from now if Barry tried to make a move on Amy... 3 years if Barry's a teacher worth his salt :P
