IHOP made the announcement via Twitter, teasing the big reveal for Monday.

"We're serious about the quality of food and our menu, and this name change really reflects that," Stephanie Peterson, IHOP's executive director of communications told USAToday.

The New York Post reported that the change is not a joke.

The "Today" show reported that more details will be released on Monday, but the famous pancakes are staying on the menu.

IHOP was founded as the International House of Pancakes in Toluca Lake, California, near Los Angeles in 1958.
