I feel compelled to follow-up
Jews for Jesus followed my friend Yosef into a single-toilet restroom to note that
Rabbi Akiva followed his teacher into the restroom and learned from him, as enumerated in
Talmud, specifically
Berachot 62a.
Rabbi Akiva said: I once followed my teacher, Rabbi Yehoshua, into the bathroom and learned three things about personal care from him.
Ben Azzai said to Rabbi Akiva: How could you dare to do such a thing with your teacher?
Akiva replied: This, too, is Torah, and I needed to learn.
