Howard带Bernadette过来一起吃饭，Bernadette对Leonard的物理实验很感兴趣，还表示要去参观。Howard吃醋了，趁Bernadette不在，警告Leonard不要挖墙脚。

Penny也产生了危机感，找Sheldon表示要学物理，了解Leonard在做啥。结果Sheldon从2600年前讲起。

Howard跟Bernadette的好事被Leonard的一条短信打断，Bernadette得知Howard如此小气，于是生气地离开了。Howard去实验室找Leonard算账，赶上Bernadette来参观，他坦诚地道歉了，得到了Bernadette原谅。

大家又一次聚餐时，Penny连珠炮般说了一段对Leonard实验的专业看法，相当令人惊讶。

Perhaps there's hope for you after all. 看来你还是孺子可教嘛

Penny详述Sheldon座位原因后得到了Sheldon的赞许

Can I talk to you for a second? 能跟你说两句话吗

Penny找Sheldon

Can we do it in private? 我们能私下谈吗

Penny要求私下谈

Here's the thing. 事情是这样的

Penny开始说

Can't you surprise him in some other way? 就不能以其他方式给他惊喜吗

Sheldon奇怪Penny为什么要学物理来给Leonard惊喜

You really are a piece of work. 你真有两下子

Howard觉得Leonard在挖墙脚

What are you talking about? 你在说什么呢

Leonard很冤枉

Don't play innocent with me. 别跟我装无辜

Howard觉得他在装

Has it ever worked? 成功过吗

Leonard质疑是否有效

Ready to get started? 准备好开始了吗

Penny准备开始学物理

How else are you gonna study for the tests? 不然你怎么考试

Sheldon还要求Penny做笔记

Can't you hold it? 你就不能憋一下吗

Penny举手要去厕所 Sheldon不满

How can you not know? 你怎么可以不知道

Sheldon很不满Penny回答不了问题

Can you just back up a little bit? 能不能倒回去一点

Penny说他讲得太快听不懂

I got a bone to pick with you. 我有事要找你算账

Howard来找Leonard算账

You text her I have a problem with her hanging out with you. 你发短信告诉她 我对她跟你出来有意见

Howard说明算账的原因

What was I supposed to tell her? 那我该跟她怎么说

Leonard说那该怎么说

Let's not get off topic. 我们别再转移话题了吧

Howard越发丢人了 他喊着别转移话题
