Legally changing your name can be a long and hard-thought process for many, but for scores of opportunists in Taiwan, all it took was a free feed to make the switch.
As part of a promotion by restaurant chain Sushiro, anyone who has the Chinese characters Gui Yu, which translates as salmon, in their name will qualify for free all-you-can-eat sushi with five friends.
More than 150 people seized the opportunity and changed their names to Salmon, prompting a warning from Taiwanese officials to think long and hard about doing so, Taiwanese media reports.
Taiwan's Ministry of the Interior confirmed it had received a surge in applications for changes to the popular fish and were far from happy about it.
"This kind of name-change not only wastes time but causes unnecessary paperwork," deputy interior minister Chen Tsung-yen told reporters.
"I hope everyone can be more rational about it."
One student who took advantage of the promotion told local news station TVBS they and their friends had eaten $300-worth of sushi for free.
Many people who changed their names vowed to change it back after the promotion. Taiwan allows people to legally change their name on three occasions.
Not everyone simply went for 'Salmon', with 'Salmon Prince', 'Meteor Salmon King' and 'Salmon Fried Rice' among other choices.
The phenomenon has been dubbed 'Salmon Chaos'.
