Every March, McDonald’s sees a surge in sales of its Filet-O-Fish sandwiches.
According to a company spokesman, it’s primarily because of Lent.
Nearly 25 percent of the sandwiches sold during the year are sold during Lent, which begins on Ash Wednesday and runs for 40 days, ending just before Easter Sunday.
The dish’s existence dates back to the 1960s, when Cincinnati franchise owner Lou Groen noticed a drop in sales on Fridays when his Roman Catholic customers were observing Lent.
Groen convinced the food chain to launch a whitefish sandwich as an alternative menu item to its popular burgers.
Since its inception, the wild-caught Alaska pollock fish sandwiches have become a McDonald’s staple.
Here are some of the craziest McDonald’s dishes from around the world:
- Bone-in pork ribs (Czech Republic)
- Fried shrimp and macaroni & cheese croquette (Japan)
- Deep-fried meat-stuffed olives (Italy)
- Nutella burger (Italy)

- Pumpkin spice fries (Japan)
- Curly crab fries (Singapore)
- Cadbury Creme Egg McFlurry (Australia, Canada, New Zealand, United Kingdom)
