Synopsis by Hal Erickson
In this episode, Fred's boss is named "Mr. Rockhead" rather than "Mr. Slate" (though his voice is still provided by John Stephenson). Whatever the case, Fred hopes to use the occasion of a costume ball to butter up his boss--and to do this, he checks up ahead of time to find out which costume Mr. Rockhead plans to wear. Once he's at the party, Fred informs a heavily diguised guest that Rockhead is a clod and a cheapstake. What Fred doesn't know is that Mr. Rockhead has switched costumes with...guess who?
