Legal Sea Foods found itself in hot water Monday after some readers said they were offended by a full-page Boston Globe ad that called Hillary Clinton a “cold fish,” all in the service of a sushi pun. The Oxford English Dictionary defines a “cold fish” as “an emotionless person,” though many readers mayalso be familiar with the phrase’s top definition on UrbanDictionary.com: “A sex partner who is either not receptive, or not providing any emotional or physical feedback during copulation.” The ad was part of a campaign featuring the company’s long-time CEO Roger Berkowitz as a faux presidential candidate, and jokingly employs much of the empty sloganeering familiar to those who follow politics and advertising. Thinkpuns like “my first act in office will be to legalize sea weed,” and “I support the gay community: that’s why we serve rainbow trout.”
