Sen. Claire McCaskill traded pranks with Sen. Ben Nelson over the Missouri-Nebraska football game.
McCaskill infiltrated Nelson's Capitol Hill office and put up various doctored photos depicting Nelson with Missouri gear. (See above)
One photo has him wearing a Missouri football helmet, another shows him with a Mizzou logo on his cheek and sporting a black-and-gold-striped tie.
