Ho, wow do I have a huge problem with this question. While they are not blameless, Hal and Lois are the most loving, most caring, most realistic parental couple on television.
I mean, shit, you've never had your parents take away some you love because you were bad? You've never had your parents put pressure on you about grades because your smart? Or because you need money? You've never been grounded because you and a friend left your sister in the cemetary after dark?
Hah!and being all around mean.
As she said in Lois Battles Jamie: "I love you, and I will do anything to protect you and keep you safe, you might grow up hating me but thats fine, as long as you're safe."
Also, for an idea, guys, lets not have this turn into an argument about the Graduation Speech, okay?
