Geeks all over the world have been getting Harley Quinn tattoos for years, but now that the character's set to make her first-ever big screen appearance in "Suicide Squad" played by "The Wolf of Wall Street" star Margot Robbie, there's no doubt that ink of the Joker's girlfriend will become more popular - and the actress is definitely helping with this!

Robbie has apparently taken method acting to the next level by doing some ink artistry herself, as new photos from the cast of "Suicide Squad" show that it's not really a matter of her getting a Harley Quinn tattoo, but rather that she's taking to inking her co-stars in full costume!

According to The Daily Mail, some of the people in the film have recently decided to get matching ink, and they're doing the needle work themselves with Harley Quinn as tattoo artist, with Robbie looking very, very serious doing the work.

The Mirror reports that the members of the "Suicide Squad" cast and crew who decided to get inked to remember their experience on the film were Will Smith (who plays Deadshot in the film), Australian actor Jai Courtney (Captain Boomerang) and David Ayer, the director of the film - and the latter was even lucky enough to get his own Harley Quinn tattoo.

Appropriately enough, the place where Harley Quinn's tattoo skills were shown to the world is called Harley's Tattoo Parlor!

According to Screen Crush, the whole thing was documented on Joel Kinnaman's Instagram, as he posted photos of Smith and Robbie working the needles, and it seems like "The Fresh Prince of Bel-Air" is no expert on the subject of inking, with Kinnaman comparing Smith's tattooing work with seeing a "drunk baby fly a helicopter."

The Harley Quinn tattoo was a fairly simple one, as they just go the word "Skwad" on their skins - could this mean Robbie's character is responsible for the many tattoos on the Joker's body?
