227 - Season 3 Episode 13 Snowbound

When Mary and Lester's flight to Hawaii is cancelled due to the blizzard, they go home only to find Rose, Pearl, Sandra and Calvin in their apt, which is one of two apts in 227 with working heat. They all stay there, including the Jenkins' cab driver, whose cab was stuck in the snow, for at least two days before everyone starts to get on everyone else's nerves. When they realize how they were acting, and that Mary and Lester had to put up with their attitudes in addition to missing their flight, they decide to recreate Hawaii in the apt for Mary and Lester.
