Honey, I'm Not Just Clowning Around

S2, E21: After muffing his chances for the last five years, Wayne makes it to the finals in the Inventors' Achievement of the Year competition with his newest invention. The Szalinski 3-I-D-er creates a holographic representation of another person around the body of the user. Rival scientist Klounberg doesn't make the cut with his device for siphoning helium from the sun to provide a cheap source for blowing up balloons. Klounberg, who wants to be King of the Carnivals, absconds with the 3-I-D-er and, masquerading as Wayne, attends the Inventors' competition in Wayne's place.
