“I’m Sorry, So Sorry” by Brenda Lee.
Explanation: This joke plays on the theme of Yom Kippur, which is all about seeking forgiveness and atonement for one’s sins. The punchline references Brenda Lee’s song “I’m Sorry,” humorously suggesting that it’s a fitting choice for a rabbi during this solemn time, as it aligns with the holiday’s emphasis on apologies and making amends.
