When Leslie finds her faulty campaign signs, the picture URL printed on them is "www.knope2012.com/imagescmyk/campaign/1239U/09230023/poster/.jpeg", which is an invalid address, it's missing a filename. However, when the clerk reads the URL off of the form, he reads out "www.knope2012.com/imagescmyk/campaign/qty1001239u/092300230992wposter.jpeg", which indeed ends in a proper filename, it does not have a slash there. The printed and spoken versions do not match, roughly the entire second half, and the printed version wouldn't work.
It's bitterly cold in Indiana in February and early March, yet the group is dress like it's springtime, including short sleeves and no hats or gloves.
