Marge: Homer, those were very thoughtful presents, but you have to tell
me where you got the money from.
Homer: All right, Marge, I'll tell you, but first you have to promise
you will not get mad.
Marge: I promise I <will> get mad, because I always do when you make me
promise I won't.
Homer: All right, if you must know. Lisa and I have been gambling on
Homer: You promised you wouldn't get mad!
