My fellow Americans! Now is a great hour in our noble nation's history, the opportunity for us to make a great sacrifice that will ring out down the halls of posterity, to make our nation truly great once again, to save the world from a peril the like of which it has never known before. So, please, give generously to the Snugglebunnies Appeal for Slightly Unhappy Children. Thank you.
