Micca - I thought at first yours was from Lord Buckley; but of course, it's not. His version of Mark Anthony went: "Hipsters, flipsters and finger-poppin' daddies. Knock me your lobes."

I remember one of the Mad Magazine parodies had Napoleon singing, to the tune of We'll Have Manhattan: "I'll conquer Russia / Then all of Prussia / I will win. / Then I'll go marching in / Berlin."

But, for some reason, the one that's stuck in my mind in its entirety is a Christmas parody, to the tune of Deck The Halls:
Deck the bars with Christmas drinking
Fa-la-la-la-la la-la-la-la
See the people getting stinking
Fa-la-la-la-la la-la-la-la
Though their brains are half corroded,
Fa-la-la la-la la-la-la-la
