Wally (Tony Dow) belongs to a boys-only school club which is putting on a "wild West" musical. Naturally, everyone in the club, including Wally, is expected to participate...and some of the boys, including Wally, are cast in "drag" as dance-hall girls. As embarrassing as this is to Wally, it is nothing compared to the humiliation endured by our hero when his brother Beaver (Jerry Mathers) stumbles upon his gorgeous showgirl costume! (For some strange reason, this episode has seldom been shown in syndication.)
