Rep. Mark Kirk has served Illinois' 10th District for a decade now. And over the years he's amassed a comprehensive voting record, attaching his name to hundreds of bills on countless topics. But HJ Res 41 could be the looniest of them all.

In a series documenting that "the more ludicrous bills that are introduced" on Capitol Hill, Congress Matters blogger Casual Wednesday outlines the details of this bill, introduced by Rep. Michele Bachmann (R-Minnesota):

Proposing an amendment to the Constitution of the United States to prohibit the President from entering into a treaty or other international agreement that would provide for the United States to adopt as legal tender in the United States a currency issued by an entity other than the United States.

Strangely, 37 House members signed on as co-sponsors -- including Kirk and fellow Illinois Republican Judy Biggert -- despite the fact that there is no real effort to create a "global currency."

Not sure how this slipped under our radar back in April. But better late than never.
