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.
