In some episodes, Rose is seen at ridiculous early hours in the morning for whatever reason (i.e. to bake or to look out for robbers). This odd talent makes sense given that she was raised on a farm, where Rose would have to wake up at hours as early as 4'o clock a.m.
In the episode "Yes We Have No Havanas", Rose tells Dorothy that Eva Braun was posing as her gym teacher during World War II. Earlier in the episode, Rose enrolls in adult high school classes because she didn't graduate. She got sick from kissing a boy with mono at a school kissing booth, and ended up spreading it to "50 other boys and a confused female gym teacher that smelled like Old Spice". Does that mean Rose kissed Eva Braun?
In the episode "Feelings," Rose reports her dentist for sexual harassment. When he does it onscreen, it's played mostly for comedy; however, Rose mentions being sedated on the previous occasion, leaving us to wonder what might have happened while she was drugged and unable to fight back.
One episode has the girls organizing a funeral for a rather despised neighbor. Only one person shows up to pay her respects...only to discover she went to the wrong funeral. She kicks the casket when she discovers whose funeral she actually attended. Shortly after the guest leaves, the funeral director comes to the girls and says the neighbor was accidentally cremated due to a mix-up. This ends up raising the possibility that the guest kicked the casket of someone she respected.
One has to wonder about how the women couldn't afford a big screen TV/cable and a pool (it's even brought up on many occasions, mostly by Sophia) but could afford their seemingly endless supply of evening gowns that pop up from time to time (which before anyone says anything, are usually bought by the women outright rather than rented or worn a time or two and then returned.)
They probably return the gowns after they attend their big events. I'm pretty sure a dress getting ruined so it couldn't be returned was a plot at least once.
Blanche owning a huge amount of evening gowns for fancy events makes at least a little sense. She mentions early in the series marrying rich and talks about how George bought her many expensive gifts when he was alive. It stands to reason that he left her quite a bit of money. She also implies that the only reason she took on renters in the first place was because it would be good for her equity, so she probably isn't strapped for cash. Rose is probably pretty thrifty when it comes to her nice clothes, especially since Blanche makes many snide remarks about them being polyester and other cheap materials that she passes off for nicer fabrics. As for Dorothy...maybe Stan just sends her a good enough alimony check that she can spend it on nice clothes for herself. I mean, he did buy her a mink stole and a $2000 diamond ring during their marriage.
Sophia being the chief complainer about their money woes may also be due to the fact she can't afford those things. She's the only one of the girls without a steady job, and frequently steals from Dorothy's purse to splurge. Dorothy mentions she tries to be very careful with money, and is probably just too practical to spring for a big screen TV/cable (she reads so much and probably doesn't think it's a worthy investment) or a pool (since that would require permits, inspections, and other headaches they've had to deal with in other home improvement-centric episodes).
