Private Snafu was a WWII US Army cartoon character in a series of War Department short subjects produced from 1943-1945. The films were intended to teach military personnel about security, sanitation, booby traps etc. and to boost morale. The Private Snafu series, directed by Chuck Jones and other prominent Hollywood animators, featured the voice of the voice of Mel Blanc as Private Snafu.
It is interesting that the obscene WWII term “SNAFU” (situation normal, all ****ed up) had already entered the accepted lexicon without apparent difficulty.
