Sunday, the Luke Skywalker actor tweeted an image of Edvard Munch's famed painting "The Scream," but with its head replaced with a cute l'il porg.This isn't Hamill's first porg rodeo. Earlier this month, he posted a photo of himself in costume as Luke, posing with a pack of porgs. (Officially, a group of porgs is called a "murder" of porgs, just like crows, director Rian Johnson has declared. Hmm, ominous.) Fans trolled right back with their own "wholesome porgnography," a phrase Hamill used in his earlier tweet. https://www.cnet.com/news/mark-hamill-the-last-jedi-star-wars-porgs-twitter/
