YMMV / The Simpsons S 25 E 8 White Christmas Blues

• Designated Villain: In order to make money Marge turns the Simpson house into a bed-and-breakfast by inviting a number of people that she had no way of accommodating and promising them things that she had no way (and no intention) of providing. Yet the tenants are the ones shown in the wrong for complaining that Marge essentially conned them out of a lot of money. At least she has the decency to apologize in the end.
• Strawman Has a Point: The point of Lisa's plot in the episode is that she buys gifts for Homer and Bart that are better-suited to her own interests: seed packets for Homer and a copy of Treasure Island for Bart. This pretty much only works if you view the episode in isolation and don't account for the kind of Hidden Depths they've shown on plenty of occasions, particularly Bart, who's enjoyed quite a few classic books under the right circumstances (if you relate it to the subplot of "The Man in the Blue Flannel Pants" two seasons prior, in which he improved his reading with help from Lisa and enjoyed Little Women, the gift seems downright sweet).
