With Gilbert (Stephen Talbot) over to spend the evening with Beaver (Jerry Mathers), Ward (Hugh Beaumont) and June (Barbara Billingsley) agree to allow Wally (Tony Dow) to attend a party at Lumpy's house while they themselves go out. The only proviso is that Wally not spend the whole night with Lumpy (Frank Bank), and that he come home at a reasonable hour. But when Lumpy finds a stain on his rug, he begs Wally to stick around until morning so that his parents won't yell at him. Dutifully, Wally calls home for permission -- but Ward and June still haven't returned yet, placing Wally in another "darned if he does, darned if he doesn't" situation. ~ Hal Erickson, Rovi
