June 15 - Our escape hit the papers yesterday, and the tabloids had a field day. On the second page of the Daily Press there was an old picture of me and a sketch of a white mouse. The headline read: Moron-Genius and Mouse Go Berserk.
"field day" の使い方が面白いですね。マスコミは事件が起きると、それが不幸な事でも、まるで喜んでいるように張り切るので、この様な場合に "field day" が使えるのですね。辞書に同じ様な例が出ているか見てみます。
Macmillan Dictionaryは "have a field day" で次の説明をしています。
to have the chance to do something that you really enjoy, especially when it causes trouble for someone else
この説明でつい最近起きた英国女王を装った偽電話事件を思い出しました。
・Merriam-Webster's Online Dictionary: a time of extraordinary pleasure or opportunity: the newspaper had a field day with the scandal
・Cambridge English Dictionary: to enjoy yourself very much or take advantage of an opportunity: The newspapers had a field day when the wedding was announced
