The Oral Talmud with Benay Lappe and Dan Libenson Episode 81

It was taught in a baraita that Rabbi Akiva said: I once followed my teacher Rabbi Yeshoshua into the bathroom, and I learned three things from him/it: I learned that one should not face east and west, but rather north and south; I learned that one should not uncover himself while standing, but while sitting; and I learned that one should not wipe with his right, but with his left. Ben Azzai said to him: Did you dare to go that far into your teacher's business?! He said to him: It is Torah, and I need to learn.

We learned in a baraita: Ben Azzai said: I once followed Rabbi Akiva into a bathroom, and I learned three things from him/it: I learned that one should not face east and west, but rather north and south; I learned that one should not uncover himself while standing, but while sitting; and I learned that one should not wipe with his right, but with his left. Rabbi Yehuda said to him: Did you dare to go that far into your teacher's business?! He said to him: It is Torah, and I need to learn.

Rav Kahana entered and lay beneath Rav’s bed. He heard Rav conversing and laughing with his wife, and seeing to his needs. He said to him(self?): The mouth of Abba (Rav's first name) is like one whom has never tasted the dish. Rav said to him: Kahana, are you here? Get out, for this is not appropriate behavior. Rav Kahana said to him: It is Torah, and I need to learn.

There was a particular eulogizer who went to eulogize someone in the presence of Rav Naḥman. He said: This man was modest in his ways. Rav Naḥman said to him: Did you go to the bathroom with him and know whether or not he was modest? As we learned in a baraita: We don't say "modest" about someone unless they are also modest in the bathroom. And what difference did it make to Rav Naḥman? Because it was taught in a baraita: Just as the deceased are punished, so too are the eulogizers and those who answer after them.
