In the final season, Barbara Eden appeared as Diana Jordan, a cousin of Mrs. Munson. Fred, Ricky & Ralph Ramsey took an immediate shine to her.

Anyway, the next night, Ricky, Fred & Ralph are far more attentive to their wives and Lucy suspects Ricky has some kind of plot involving Diana. Lucy, Ethel & Betty Ramsey end up leaving the boys behind at the country club and drive home angry.

Around 1:30am the girls are looking to see if the boys were coming home and Lucy said "Not yet".

Now we know that all 6 of them took the same car to the country club. If Lucy drove home with the girls, leaving the boys behind, how would they have gotten back home again? Taxi? Hitch a ride with the Munsons? Walk home?
