Google fails me on this one, but allegedly Butz once characterized blacks as wanting only three things - "a tight pussy, loose shoes and a warm place to shit". He wound up resigning before the end of his administration (Nixon/Ford).
Do they still print mass market ethnic joke books? I don't recall seeing any for quite a while. There was a big series by Larry Wilde, but Amazon says they're all out of print but for his Dumb, Dumber, Dumbest joke book.
These books used to be on sale at places like K-mart. And they sure were funny.
