Doonesbury by Garry Trudeau for October 26, 1971
Mike: Say, Calvin, if you 'could have your choice, would you rather be black or white? Calvin: Gee, I'm not sure. I know I wouldn't want to be white...on the other hand, being black is no barrel of laughs. I suppose I could compromise..you know, be a Puerto Rican or an Indian..geez, I don't know...Actually Mike, it's pretty stupid question.
