As they gleefully toss lists of campaign promises into the Eternal Flame of Tyrannical Rule, the legislators joyfully sing the classic Washington DC hymn. to the tune of Auld Lang Syne
May all our promises be forgot
and never brought to mind.
May all our promises be forgot
Now let's get faced on wine.
