In a previous episode ("The Pagan Rite") Barbara was furious when she thought Tom had taken freelance work to help pay their bills, saying that their efforts in self-sufficiency should be all or nothing. But in "A Tug of the Forelock" she is the one who suggests they take on temporary work to afford petrol for their new vehicle. But the operative word here is, "temporary". Tom explains to Jerry that this was not a "permanent state" and therefore not a breach of self-sufficiency. This principle was first presented by Tom in "The Pagan Rite" where he explains taking "one job for one purpose" is an acceptable exception.
