Dating Rav's Daughter

יבמות מה.

ואף רב מורה בה היתירא
דההוא דאתא לקמיה דרב אמר ליה "<עובד כוכבים> {גוי} ועבד הבא על בת ישראל מהו?"
 אמר לו "הולד כשר"
אמר ליה "הב לי ברתך!"
"לא יהיבנא לך!"
אמר שימי בר חייא לרב "אמרי אינשי גמלא במדי אקבא רקדא הא קבא והא גמלא והא מדי ולא רקדא"
א"ל "אי ניהוי כיהושע בן נון לא יהיבנא ליה ברתי"
א"ל "אי הוה כיהושע בן נון אי מר לא יהיב ליה אחריני יהבי ליה האי אי מר לא יהיב ליה אחריני לא יהבי ליה!"
לא הוה קאזיל מקמיה יהיב ביה עיניה ושכיב 

Yevamoth 45a

Rav was also of the opinion that if the father of a child is not Jewish, the child is not a mamzer. One guy (who had a non-Jewish father) once asked Rav, "Am I a mamzer or am I kasher?"

"You're okay." Rav told him.

"Great," the guy responded to him, "I want to marry your daughter!"

"I'm not giving you my daughter." Rav retorted. 

Rav Shimi b. Hiya told Rav, "Put your money where your mouth is!"

"Even if this guy was the next Yehoshua bin Nun I wouldn't give him my daughter!" Rav declared.

"If I was the next Yehushua bin Nun," the guy told him, "I wouldn't need your daughter! I could have any girl I wanted!"

The guy wouldn't get out of Rav's face, so Rav gave him a dirty look and he died. 

Moral of the story: Don't be too persistent when you ask out Rav's daughter or he'll literally (well, maybe not literally) stare you to death. 

Buried Alive

מסכת שמחות ריש פרק ח

יוצאין לבית הקברות ופוקדין כל המתים עד שלשים יום, ואין חוששין משום דרכי האמורי. ומעשה שפקדו אחד אחר שלשים יום, וחיה עשרים וחמש שנים ואחר כך מת, ואחר הוליד חמשה בנים ואחר כך מת.

Masechet Semachot Ch. 8

One may go to the cemetery and check up on the deceased 30 days after burial, and we are not concerned that this practice stems from non-Jewish customs. They once checked up on a dead guy 30 days after they buried him, [found him to be alive,] and he lived for another 25 years. There was another guy who fathered five children.

In the 18th century, a government in Europe tried to pass legislation that would delay the burial of a deceased person for a few days to confirm that he is indeed as dead as a doorknob. Moses Mendelssohn tried to use this berayta as a proof that this claim is, in fact, a legitimate one and that the European law should be observed as a measure of pikuach nefesh. The Chattam Sofer and others argued that even though one or two incidents have indeed occurred, they are not definitive enough to require us to disregard the halacha that instructs us to inter the deceased immediately. (The teshuvot can be found in the Pitchei Teshuva Y"D 357:1)
