Doonesbury by Garry Trudeau for January 21, 1975
Duke: MacArthur, you don't really still sacrifice virgins to the volcano, do you? MacArthur: Oh, yes, sir! The volcano has been very good to us - no eruptions in 2,000 years! It's our little way of saying thanks! Duke: And the people can still relate to such a brutal custom? MacArthur: Well, a few of the kids are a bit put off by it. But most older Samoans still view the sacrifice as a major event on their social calendars! Duke: Hmm... how often is it held? MacArthur: Generally speaking, we limit it to one sacrificial virgin a month. Of course, there are exceptions. Duke: For instance? MacArthur: Well, like, the night Nixon resigned, we had a double-header.
