When Cody is counting his money, he says "ten spot" indicating a ten dollar bill, but he holds up a one dollar bill.
Carol lectures Karen about how hurt Freddy will be by her dumping him, and a lot is made of Karen's shallow reasons for doing so. However, Carol forced Karen into the date in the first place - without her consent and against her will. Karen even quite reasonably points out Carol herself told her she has the right to make her own choices about who to be with, but then Carol shames her for doing exactly that. It's entirely overlooked that in taking away her daughter's choice, Carol is the one responsible for hurting both Freddy AND Karen. This is a huge oversight for a show filled with a family learning life lessons.
