When they were mad at France, the U.S. House of Representatives changed "french fries" to "freedom fries" on their cafeteria menus.

This was back in 2003, when France refused to take part in the Iraq war. They also started referring to french toast as "freedom toast". According to one congressman, the name change was "a small but symbolic effort to show the strong displeasure of many on Capitol Hill with the actions of our so-called ally, France".

Political menu changes have happened in the past. U.S. restaurants in World War One started calling sauerkraut "liberty cabbage" to spite Germany.
