Trivia: Originally, the segment "The Crate" (the story about a man-eating monster that lives in a crate) was supposed to be the film's third story, while "Something To Tide You Over" (the story about the drowned lovers who come back from the dead to take revenge) was supposed to come after "The Crate" and just before the last story, "They're Creeping Up On You." George Romero decided the film would flow better if "The Crate" came in fourth instead of in the middle.
Answer: Besides being in "Father's Day", it showed up in "The Lonesome Death Of Jordy Verrill" right next to the cash box at the Department of Meteors.

In "They're Creeping Up On You", Upson Pratt uses it as a soap dish. And in the epilogue, it appears on Billy's desk when he starts stabbing the voodoo doll.
