In the episode where Didi, Stu, Charles,and Betty are taking the test to see if their child is a spoiled brat, the book says "15 Ways To Find Out If Your Child Is A Spoiled Brat". Yet when Chuckie's dad read them off, he states 50 WAYS. this is a pretty big mistake.
Then again, Angelica is a *HUUUUGGGEEEE* spoiled brat. She could get perdrillions of checks. (My friends and I made up perdrillions in second grade. It means about as much as infinity.)
Nice slip-up catching...I liked that episode, especially the question "Has the SWAT team ever responded to any of your child's temper tantrums?" It wouldn't be that funny but there is the fact that is HAS happened to Angelica. LOL
Also, in that episode, when Drew is counting up his checks, the checks take up both sides of the paper. If Angelica covers 49 out of fifty questions, then I am sure both sides of the paper would NOT be filled up with checks. About one half to three-fourths of the first side would probably be filled up.
