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。
