The Lil' Gang doesn't want the Lil' Dems to ruin St. Patrick's Day with their liberal and tolerant St. Patrick's Day float. They enlist the help of Lil' Karl Rove (voiced by Kevin Federline), who gives them advice and does some bad rapping as his alter-ego, MC Rove. Meanwhile, first lady Barbara gets a tanning bed and inadvertently cooks her liver.
