Halloween, the Super Bowl, New Year's Eve, New Year's Day, and you guessed it, the night before Thanksgiving. These are the most popular days for ordering pizza.

Pizza parlor Pizza Nola says it's a busy day for them because folks are busy cooking for Thursday and don't want to worry about dinner for Wednesday.

Why the hashtag? 'Cause it's a thing.

Pizza Hut says they plan to sell 1.2 million pizzas on the Wednesday before Thanksgiving.

Also, Papa John's is offering 50 percent off online orders with a special promo code.
