The lame duck congress had to do something after "Chinese Credit Rating Agency Downgrades the Entire United States".
They moved pretty fast:
WASHINGTON, DC—In a move designed to make the United States seem more "bad-assed and scary in a quasi-heavy-metal manner," Congress officially changed the nation's name to the Ünited Stätes of Ämerica Monday.
"Much like Mötley Crüe and Motörhead, the Ünited Stätes is not to be messed with," said Sen. James Inhofe (R-OK). An upcoming redesign of the Ämerican flag will feature the new name in burnished silver wrought in a jagged, gothic font and bolted to a black background. A new national anthem is also in the works by composer Glenn Danzig, tentatively titled "Howl Of The She-Demon." Source
