Comment(by miqrogroove):

 I added {{{var_dump($_GET);}}} to the default single.php template to test
 Viper007Bond's claim that ampersands are arbitrarily parsed into query
 variables.

 First I tried hitting /2010/01/testing-123/&oogabooga/ and that path was
 treated as identical to the front page o_O  The single.php template didn't
 even load, so that was a total failure.

 Next, I tried hitting /2010/01/testing-123/&oogabooga/page/1/ and that
 path was forwarded to /2009/12/testing/ for no apparent reason.  Another
 canonical failure.

 Thirdly, I added {{{var_dump($_GET);}}} to the index.php template and
 tried hitting /&oogabooga/ which was also treated as indentical to the
 front page.  The output was as expected array(0) { }
