They parodied Johnny Cash's I don't like it (But I guess things happen that way)

some of the lyric:

Our last record wasn't a hit
They forgot to put a hole in it
I don't like it but I guess things happen that way
The reason that it never sold
It's a nine inch record with a twelve inch hole

Johnny Cash made this a hit
We're gonna put a stop to it
He don't like it, but I guess things happen that way
&c. &c.
And, in their performance of Bismarck, they did the line "Our souls were full of hope" by singing "And our holes--our souls--were full of hope" haha those guys were SO funny, and great musicians!
