Mary's ex husband leaves a message on the family answering machine that he's coming to town and would like to visit. This raises all kinds of feelings in the family. The two young daughters are looking forward to seeing their dad again. (the younger of the two has a dream that he's going to bring her back a kangaroo) The son David is certain that he's only going to disappoint them again (he had a habit of not showing up for things he said he would attend) And Mary just wants to show him up and make him eat his heart out with what he's missing out on. Billy isn't entirely sure himself how he feels, but it all comes spilling out when he mistakes a visiting IRS agent dropping by for a home visit for the ex-husband. This ends up being good for Billy as the IRS agent is convinced that no one in a fraudulent marriage could have such strong feelings for his wife.
