Summary[]
The trio decides to celebrate Christmas at home because they haven't been invited to any parties, even by their neighbors the Stevens. The Ropers invite them downstairs for a party, and they accept, but moments afterwards the Stevens call to reconfirm their invitation to the party, which must have been lost in the mail.
Jack and Janet want to go, but Chrissy makes them fulfill their obligation to go to the Ropers'. The evening is spent listening to Roper sing silly songs, 'til finally the kids are able to excuse themselves. They go off to the Stevens' where they run into the Ropers, who also found out too late that they had been invited. Roper had spent the evening trying to bore them into leaving so he and Helen could go to the party.
