In this section Private confuses, "veterinarian" with "veteran". In case you were wondering, the thermometer gag was in the script.
While working on this project I was reminded of the many educational cartoons I had seen in my youth. Many of the ones done by Disney were awarded Oscars. Toot Whistle Plunk Boom and It's Tough to be a Bird to name a few. Donald in Mathmagic Land is another favorite. Warner Brothers made a number of shorts for the troops featuring Private Snafu. (Voiced by Mel Blanc.) Many of these used ribald humor to get their message across. One such cartoon warns the men to be on the look out for booby traps. You can imagine.
