Penny receives an unwanted visitor from Nebraska named Christy. In Penny's eyes, Christy is a loose woman with no morals. Hence, Christy is ripe for the picking by Howard. As Howard and Christy have a spontaneous get together using Penny's bedroom, Penny decides to ask Leonard and Sheldon if she can sleep overnight at their place, which elicits different responses from Leonard and Sheldon. Beyond Penny's sleeping problem, Howard hooking up with Christy causes more issues. First, Leonard, Sheldon and Raj are now missing a fourth in their regular activities. And second, they can all see that Christy is only using Howard. They have to figure out how to get Howard back. Written by Huggo

Did You Know?


Sheldon (Jim Parsons) states that if he could afford the rent he'd ask Leonard (Johnny Galecki) to leave. In episode 2.14, The Big Bang Theory: The Financial Permeability (2009), Sheldon states that his expenses account for 46.9% of his after tax income. As expenses must include his rent, clearly he can afford the rent on his own assuming a roughly 50/50 agreement with Leonard. See more »

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 »

The Dumpling Paradox
18 June 2017 | by lu-68795See all my reviews

I'm really liking this show, i just started it and is truly good. This was a funny episode. When Penny's friend Christy comes to the town, she is picked up by Howard, and his affair takes up all of his time, leaving no space for his normal activities with the gang. It was specially funny for me the routine of Sheldon at 6:15 PM, and how Penny joins them to play Halo and she's very good in it.

Good episode, the show it's getting better and better after each chapter!
