A Rabbi Akiva story -- wherein he didn't know the answer to 3 questions, though others in the beit midrash were able to shed light for him. (One of these questions being a straight-up "avodah zarah" Jew/non-Jew interaction question, and the possibility of rehabilitating jugs owned by a non-Jew, which explains the passage's presence on this daf). Also, more on the fish stew -- and the story of how guards were placed to guard the fish stew to make sure nobody added wine to it (risking libation wine, etc.). Note that "cheap wine" was understood to not be problematic to begin with. Plus, the cases of cheese and the woman who is betrothed with the excrement of an ox that awaits stoning.
