The home of the Whopper announced on Wednesday that from Feb. 28 through March 1, customers can get a free Whopper or vegetarian Impossible Whopper with a purchase of $3 or more on their mobile app.

This whopper was spotted in Montana in January 1887, when ranch owner Matt Coleman reported seeing snowflakes “larger than milk pans” during a severe storm. Admittedly, some experts are sceptical.
