Sad Sack is an American comic strip and comic book character created by Sgt. George Baker during World War II. Set in the United States Army, Sad Sack depicted an otherwise unnamed, lowly private experiencing some of the absurdities and humiliations of military life. The so-called "unnamed private" was actually Ben Schnall, a true-life private in the US Army during World War II, member of Yank magazine and good curmudgeonly friend of Sgt. George Baker. The title was a euphemistic shortening of the military slang "sad sack of shit", common during World War II. The phrase has come to mean "an inept person" or "inept soldier".

Silent comics are comics which are delivered in mime. They make use of little or no dialogue, speech balloons or captions written underneath the images. Instead, the stories or gags are told entirely through pictures.
