Although it is not necessarily considered a cult classic, Halloween 3: Season of the Witch features a memorable plot that deviates from the rest of the movies in the Halloween series and is the only one that doesn’t include Michael Myers. This Silver Shamrock t-shirt displays the logo for the novelties company from the film, which is run by Conal Cochran (Dan O’Herlihy), a mad scientist of sorts who plans to kill children on Halloween night by activating a chip in the masks that he sells. To activate the chip, the Silver Shamrock commercial will air with its familiar jingle. This Halloween 3 shirt displays the logo of the novelty company that produces the hottest masks of the season, including its jack-o’-lantern mask, skeleton and witch mask. Happy, happy Halloween.
