Married with Children1987

Bud Bundy:
You have to understand, Kelly's brain can hold anything. But there are some things you have to know. One: that it's totally empty.

Al:
Woudn't you know it.

Bud Bundy:
And two: that you can't just shove information into her head. You have to be careful. Feed her information slowly, bit by bit, drop by drop, until she's full.

Al:
Full?

Bud Bundy:
Oh, yeah. Kelly's brain can actually get full with information. And then you got to be really careful. Because each new thought after that will totally replace an old one. That's why Kelly forgot to wear a blouse on the day she went to take her drivers ed exam.
