Doonesbury by Garry Trudeau for February 28, 1977
Professor: Okay, class, let's all settle down! Dr. Kissinger will be here in a few minutes! Zonker: Hey, man, why us? I thought he was being fed to the grad students. Professor: Well, it seems most of them still remember the trashing of Indochina. It was thought you freshmen might be a little less hostile. Zonker: Sound reasoning! Barney: Not so! My older brother told me all about the war before he left to grow cabbages in Vermont! Zonker: Don't worry, Barney, you're still the ultimate freshman. Professor: Okay, now, if we could all just sit up straight... Barney: I am? Zonker: Hell, yes. Even I find you refreshing!
