7.3 The Scavenger Vortex Competition has always been a great foundation for a sitcom episode (examples are more than plentiful, but kids, the all-time classic is probably Friends’ The One With the Embryos; while Phoebe is off getting impregnated with her brother’s babies, everyone else spends all day on a quiz about each other’s habits. It’s funnier than it sounds). The Big Bang Theory has got good mileage out of the concept before, particularly successfully in the pie-based climax of The Re-Entry Minimization. To squeeze more juice out of the concept, then, the show needed to shake things up a bit. It does so by, as in the season premiere, offering a mixed platter of old relationships that always work well (Penny/Sheldon) with some fresh pairings that provide an opportunity for new material (Amy/Howard, Bernadette/Leonard). Penny and Sheldon’s chemistry is as good as ever; Leonard is mostly playing straight man to something we’ve seen before, Scary Bernadette, but Scary Bernadette is always welcome, especially when she gets quietly mad. Her delivery of “a willow” is great. Bubbling underneath it all is a conflict that’s been running since the first season, as Leonard and Penny try to negotiate their feelings about his over-education and her lack of same. As this episode clearly demonstrates, Penny is neither stupid (she’s just as intelligent as everyone else if not more so) nor completely ignorant (she can use liability correctly in a sentence, after all). If only Leonard – and everyone else, but especially her boyfriend – could accept that, and Penny could have some faith on her own brain-power, they’d all be a lot happier. But then, happiness makes for dull television. The main criticism that could be levelled at this episode is probably that the stakes are so low. Leonard and Penny’s conflict is on-going and won’t be resolved by the end of the scavenger hunt, and unlike the classic Friends example (by the end of which four characters have actually swapped apartments) there is ultimately no point to any of it. Bu then, that was how Raj planned it – because the point isn’t what you get out of it at the end, the point is to enjoy spending time with friends and have fun. That’s what this episode aims to do, and it does it very well. Follow our Twitter feed for faster news and bad jokes right here. And be our Facebook chum here.
