Wish I’d thought of this first:
On Gambling Problems
From the episode “$pringfield (Or, How I Learned to Stop Worrying and Love Legalized Gambling)”:
Homer: You know, Marge, for the first time in our marriage I can finally look down my nose at you. You have a gambling problem!
Marge: That’s true. Will you forgive me?
Homer: Oh, sure. Remember when I got caught stealing all those watches from Sears?
Homer: Well, that’s nothing, because you have a gambling problem! And remember when I let that escaped lunatic in the house ’cause he was dressed like Santa Claus?
Homer: Well you have a gambling problem!
