It's a trap!
Mark Hamill celebrated May the 4th (aka Star Wars Day) with some light-hearted pranks for some of the Force's most loyal devotees, that resulted in meeting Luke Skywalker himself.
"I've rounded up some superfans for something special," Hamill says in the video. "They think they're here to read some classic Star Wars lines for a video celebrating the 40th anniversary. But what they don't know, is that I'll be their surprise co-star."
Watch the video below to see how the fans reacted to the stunt.
Priceless! This really is the perfect way to reach out to the beloved franchise's die-hards.
Elsewhere on May the Fourth, Jimmy Fallon did some musical re-editing on Wednesday's Tonight Show, cutting together footage from previous Star Wars films to make the original cast do a rendition of Smashmouth's "All Star."
Random? Absolutely. But still a welcome addition to Star Wars Day.
Meanwhile, in honor of May the Fourth, ET asked a bunch of Star Wars actors what "The Force" means to them.
