Elliot Stabler: I've got to get home. My pregnant wife has a craving for peanut butter and tacos.A Pregnancy Trope. During any pregnancy, at some point the mother will experience cravings — however, they will never be cravings for any standard foodstuff (such as pickles, ice cream, etc), but will instead be cravings for the most hilariously inappropriate and mismatched foods (chocolate covered kippers, boiled eggs and ice-cream, peanut butter-dipped pickles, etc). Bonus points are awarded if the woman craves something that is either (a) extremely difficult if not physically impossible to find; (b) isn't actually ''food'' or (c) both. The trope often involves the father being roped into visiting late-night markets at 3 AM in search of that particular brand of pickled radishes and pistachio-flavored ice cream. Usually, this state of affairs will result in the father being stretched to breaking point to find the necessary goods... only to find, when he returns home, that the mother no longer craves it (usually without so much as a "thank you for traveling across five states and climbing a mountain to get it"). A case of Truth in Television — some women actually do crave inedible things during pregnancy - but it tends to be exaggerated in fiction. In many cases, a woman doesn't even have to be pregnant. Some are prone to wild cravings during "that time of the month," to the confusion of any men present. This is probably a milder form of a condition known as "pica"; those afflicted with full-blown pica will crave all sorts of bizarre stuff 24/7, regardless of gender. Compare the Extreme Omnivore, someone who always eats this way (e.g. the aforementioned full-blown pica). A rarer variant of this trope is where the "wackyness" of the cravings have less to do with the substance desired and more with the sheer quantity desired. In this form of Wacky Cravings, the comedy is how "eating for two" turns into something more like "eating for two dozen", where the pregnant woman becomes a voracious glutton who uses her pregnancy as an excuse to eat like a pig, thus turning even the most prim and diet-minded expectant woman into a shameless Big Eater.

- A print ad from the 1970s for Camel Cigarettes — whose tag line was "I'd walk a mile for a Camel" — had a picture of a man next to a jar of pickles and an empty box of vanilla ice cream, and in this case it was not that he had run out of cigarettes, which is why they usually had to leave. The caption at the bottom, "Start Walking", meaning in this case he had to walk a mile for a half-gallon of ice cream for his (presumably) pregnant wife instead of for his cigarettes.
- One ad had a pregnant woman ask her husband to go out for something *insert adjective ending in "ewy" here*, adding a different quality even as he's getting in the car.

Queue Answer Cut to fifteen minutes ago where his very pregnant wife admits "they're" craving fried chicken, eggs, and bacon at 8pm on a Tuesday (not exactly brunch hours).

- Subverted in The Pact: The fridge mysteriously opens in the night, and some food is scattered on the floor: a jar of pickles and two sticks of butter. Is this a clue that the ghost is a pregnant woman? Well, yes. But she's not the one who made the mess; the flesh-and-blood killer was just hungry.
- In The Belgariad sequel series The Malloreon, during Ce'Nedra's pregnancy, she got these sorts of cravings, mainly just to mess with Belgarion. In a subversion, it was never a problem, since Garion (a sorcerer) could simply create whatever food she wanted out of thin air.

And in a textbook example of the trope, it turned out that Laure could not even stand the sight or smell of the fruit.
- During Alisande's pregnancy in A Wizard in Rhyme, she finds herself craving a hot fudge sundae. The "wacky" part comes from the fact that she lives in an Alternate Universe medieval France where ice cream doesn't exist, so all she can do is describe a food she that she doesn't even have a name for.
Live Action TV
- Almost any 1970s British sitcom that featured a pregnancy at some point was required by law to feature these.
- An episode of The Brittas Empire once featured a pregnant woman eating coal.
- The same thing happens in Two Pints of Lager and a Packet of Crisps, when Louise is pregnant. She takes out a large lump of coal and bites into it as one would an apple.
- In Latin America, this trope is often coupled with the old wives' tale that if you don't satisfy the craving, the kid will be born with a physical symbol of that unsatisfied desire, giving this trope a bigger sense of urgency. In one old Sketch Show, a man tried to discredit that old tale, saying that while his mother was expecting him she craved watching Tarzan movies (in an age before home video, when those movies were not available anyway), but he was born and grew up healthy and normal... and then he makes the archetypical Tarzan yell.
- In non-humorous examples, the mother having a bizarre craving can be a sign that Something Is Terribly Wrong.
- In V (1983), Robin, pregnant with a hybrid, craves red meat to the point that she wakes in the night and yanks it uncooked from the refrigerator to eat. Or, in the 2009 remake V (2009), Valerie (also pregnant with a hybrid), almost eats a mouse caught in a trap.
- In 'Demon Seed'', the mother of the titular child, conceived through similar methods, also craves red meat to the point of eating it raw.

- On Sesame Street, during Maria's pregnancy with Gabriella, her cravings led her to try Grouch cuisine, which is always depicted as very disgusting mash-ups such as marshmallow sauce over fish — and she loves it, much to Oscar's delight (and Luis's disgust).
- An episode of Xena: Warrior Princess finds Xena, Gabrielle, and some young friends ordering food in a tavern. Xena orders something extremely bizarre that everyone else notices except her. Later it's revealed that she is pregnant with Eve (no, not that Eve).
- Parodied in Scrubs when Dr Cox brought Jordan a live goat.
- Star Trek: Voyager features this, during the episode Elogium where Kes goes through false puberty and her body readies for conception.

- When Lucy is "expecting" Little Ricky on I Love Lucy, she sends Ricky out in the middle of the night to find a store that makes a papaya milkshake — as well as sardines to mix in and a pickle to dip in it. At the end of the episode, she's switched to sardines with pistachio ice cream and hot fudge. In Real Life, the ice cream and fudge were "played" by mashed potatoes and gravy - but the sardines, which had to show up on camera for effect, were the genuine article. Lucille Ball later said she never ate sardines again after that.
- In one episode of Three's Company, Cindy is Mistaken for Pregnant by Jack and Janet. One thing that supposedly confirms their suspicions is when Janet sees Cindy making a tuna fish and jelly sandwich.

- Before the modern days of decent nutrition, pregnant women would crave for chalk — it contains calcium, which is necessary to build up the bones and teeth of the baby.
- Geophagy (eating of dirt and clay) still happens with pregnant women in some poorer countries, and parts of the U.S. South.

- Chalk isn't even that unusual. Flavored chalk is commonly used as an antacid. It's even recommended as a calcium supplement.
- Vegetarian Kari Byron had a craving for beef stew (her mom's recipe) while she was pregnant. Her husband got stuck with the job of preparing it.
- In the Babylonian Talmud, Chapter 82a of Tractate Yoma mentions pregnancy cravings for non-kosher food. The passage discusses a pregnant woman who craves pork on Yom Kippur!

Still, check with your rabbi first.)
- Some hypothesize that various isotopes, such as Carbon-13, are necessary for long-term health in a baby.

- Non-pregnancy example: Many people on diets will crave one bizarre thing or another. Sometimes it's simply missing a favorite food, but sometimes, especially if the craving is pretty odd, it could be that the way they've structured their diet has left them lacking in some vital nutrient.
