Sheldon辦公室出現(xiàn)一個(gè)美女，所有人都來(lái)圍觀任斋，期待被介紹继阻。沒想到她就是Sheldon的孿生妹妹Missy。大家都迫不及待向Missy發(fā)出求愛信號(hào)废酷，無(wú)奈太不合時(shí)宜——Raj自豪地宣稱印度人發(fā)明了睡衣穴翩，Howard則聲稱猶太人發(fā)明了割禮，Penny出馬帶Missy去做美甲锦积，才算擺脫困境芒帕。
Leonard跟Sheldon密談，請(qǐng)他關(guān)注妹妹的婚姻大事丰介，不可所托非人背蟆。Sheldon想到妹妹或許有潛在的基因生出一個(gè)2.0版Sheldon鉴分，頓時(shí)熱心起來(lái)。他出面排除了打得難分難解的Raj和Howard带膀，前者具有說(shuō)話障礙志珍，盡管最近服用了藥能對(duì)女生說(shuō)話了，但留下了不斷擺手的后遺癥垛叨，排除后者是因?yàn)樗莻€(gè)離不開老媽的小男人伦糯。Leonard正沾沾自喜，Sheldon轉(zhuǎn)頭就說(shuō)他由于乳糖不耐癥也出局了嗽元。并且當(dāng)場(chǎng)拿了塊芝士對(duì)他說(shuō)只要他吃了不放屁（顯然不可能）敛纲，就可以跟Missy上床。
Missy和Penny回來(lái)在門邊剛好聽到這話剂癌，和Sheldon談了一陣淤翔，然后教訓(xùn)得他出來(lái)宣布此事他不管了。
三個(gè)人決定公平競(jìng)爭(zhēng)佩谷，在電腦游戲里面比賽旁壮。Leonard勝出，去約谐檀，失敗了抡谐。Howard去，也失敗桐猬。Raj剛敲開門對(duì)Penny說(shuō)了半句話童叠，就說(shuō)不下去了，藥效過(guò)了课幕，最后Missy出來(lái)，同情地看著他一言不發(fā)地默默轉(zhuǎn)身下樓了……
