To get a couple back together
[ALF and Lynn are trying to get their parents to stop fighting]
ALF: To get a couple back together on Melmac, we'd recreate the happiest moment of their marriage.
Lynn: I wonder what Mom and Dad's happiest moment was.
ALF: The day they met me?
Lynn: Think again.
ALF: The day after they met me.
Lynn: Keep thinking.
ALF: I can't. My brain hurts.
