据外媒报道，汉堡王（Burger King）9月17日宣布，将于 “国际和平日”（International Day of Peace）与其它四家连锁餐厅联合推出怪物汉堡，以引发公众对和平日的关注。
汉堡王称，截至目前为止，丹尼斯（Denny's）、韦巴克汉堡（Wayback Burgers）、翡翠（Krystal）和巴西汉堡连锁店Giraffas已经同意相应其提议，提供各自的汉堡食谱，共同创造一个怪物汉堡（Monster Burger）并于9月21日国际和平日当天推出。

Burger King officials announced Thursday that they will team up with Denny's, Wayback Burgers, Krystal, and Giraffas to give away 1,500 “peace day burgers” at a pop-up restaurant in Atlanta on Sept. 21.
The Peace Day campaign was launched last month when BK took out full-page ads in the Chicago Tribune and New York Times calling on McDonald's to join them in a one-day cease-fire in their “burger wars” by collaborating to make a McWhopper （a hybrid of McDonald's Big Mac and Burger King's Whopper）。 Burger King suggested that the mashup burger could be sold to raise money to benefit Peace One Day, a non-profit organization campaigning to raise awareness of Peace Day, a United Nations recognized day that will be celebrated on Monday.
