In "Is That Kosher?," Arthur suggests that if Francine has trouble with fasting, she should contact his friend, Adil, who fasts for a whole month during Ramadhan. Adil is a pen-pal of Arthur's who was introduced in the eighth season story "Dear Adil." Francine ultimately does write to Adel, who suggests that being with friends could help. Francine takes his advice, but ends up being at Arthur's when his pizza party is in full-swing.
Something to note, however, is that the monthly fast of Ramadhan is only observed during the hours from sunrise to sunset-- not actually going without food for a full month.
Postcards from You: The first postcard is from Madeline ("Maddy") of Oceanside, California. She visits a farmer's market with her family, where they pick out various fruits, vegetables and flowers. The second postcard is from Katelyn in Franklin, Massachusetts. She shows viewers her method for making and decorating cookies.
Binky reads the title card for "Is That Kosher?" It's the one where Francine gongs the title card, rattling Arthur. Muffy reads the title card for "Never, Never, Never." It's the one where D.W. flies in wearing blankie as a cape, spinning Arthur around.
Tommy: Sure you can play with your toys, D.W. We've got a really good game planned with them today. (He and Timmy toss mud at the toys.)
D.W.: What are you doing?
Tommy: Playing "ambush." Today it's trolls vs. unicorns.
D.W.: Listen up, everyone! I have an announcement to make. I'm giving away all of my toys. And all you have to do to get 'em is to tell me how much you love me.
Bubba: Let me guess. Ya' ate some of Arthur's pizza, right?
Francine: It's that obvious?
Bubba: Bubbas know these things. Plus, there's a mushroom on your shirt.
Francine: Wow. I'm not even hungry. This is going to be easy.
Katherine: Oh yeah, fasting is a piece of cake. Easy as pie. Or should I say pizza pie.
Francine: I know what you're doing. And it's not going to work.
Francine: (explaining the rules of fasting for Yom Kippur) Nothing at all for 25 hours.
Buster: I don't think I've gone without food or water for 25 minutes.
(During an opening fantasy sequence, Francine attempts to eat a fruit from an oasis, but is accosted by a hooded figure...)
Hooded Figure: Drop that fruit!
Hooded Figure: Because I said so, that's why!
Francine: Well, that's not good enough! I'm starving! Who are you, anyway?
Hooded Figure: (lowers her hood) You!
Francine: (gasps and looks askance at the camel she rode in on) But why would I want to keep myself from eating?
Camel: Don't look at me. This is your meshugeneh dream, not mine.
Is That Kosher? was nominated for an Emmy Award for Outstanding Performer in an Animated Program - Joan Rivers.
The Yom Kippur fast is surely 25 hours long, as was said in the episode, but until 20 minutes after the stars' appearing, and starts 20 minutes before the sunset. If it was from sunset to sunset, it was only 24 hours long.
Bubba can also be seen in the special "Arthur's Perfect Christmas" among the many Frensky family members during the Hannukah blessing scene.
(Francine has just given up on the idea of watching television to distract her from her hunger, after her channel-surfing leads her to nothing but cooking shows or advertisements about food.)
Francine: Okay, TV was a bad idea. I know. I'll read. (She begins browsing titles on the family bookshelf.) Food of the Goods?! Breakfast at Tiffany's?! Who Moved My Cheese?!
In searching for reading material, Francine comes across books with food words in their titles, though only one of them actually has a plot particularly involving food. Food of the Gods, first published in 1904, is a scientific romance about a food that causes animals to grow into giants. Breakfast at Tiffany's is a novella by Truman Capote about writer's memories of a call girl named Holly Golightly. Finally, Who Moved My Cheese?, first published in 1998, was written by Spencer Johnson and is a sort of fable designed to help readers deal with workplace change.
