The temptation to crash a stranger's bar mitzvah at a local hotel is too much for Roseanne as she drags Dan out on the town for a "last hurrah" before the baby is born.
Roseanne and Dan decide to go out on the town one final time before the baby is born. After finding out that their diner table at the nice hotel they're staying at will be unavailable for quite some time, they crash a Bar Mitzvah taking place in the private dining room. Becky and Darlene discover a bottle of peppermint schnapps at the restaurant after closing and get wasted.
