During an interview one day, Groucho Marx was asked whether there was any hope for President Richard Nixon. "The only hope for Nixon," Groucho sarcastically replied, "is his assassination."

"This interview became quite popular and was republished in several other magazines," the photographer Robert Altman later recalled. "It finally caught the attention of the United States Attorney General's office. They proceeded in raising Cain by threatening Groucho, demanding a retraction and apology for this, by now, well known incident."

The result? "Well nobody leans on Groucho... so he hung up on them. Whaddaya gonna do... arrest Groucho Marx?"
