Bullseye!

When Dad heads out to attend a speaking engagement on antiques, he unwittingly finds himself participating in the L.O.V.E.M.U.F.F.I.N. Pageant of Evil against Dr. Doofenshmirtz and Rodney. As a special host oversees the proceedings, Perry is tasked with monitoring the situation, but Dad gets hit with Rodney's "Evil-inizer," and is crowned the supreme leader of L.O.V.E.M.U.F.F.I.N. Meanwhile, Candace is determined to bust the boys but doesn’t realize that they are actually helping with Mom's modern art installation. Across town, the boys are playing a giant game of darts.
