Over the summer, photos surfaced of the Suicide Squad cast making their bond very permanent with the help of a few “skwad” tattoos. Some of those were inked by Margot Robbie herself (as seen in this snapshot of her in full Harley Quinn makeup, tattoo gun in hand), including one she admittedly misspelled.

During the post-Super Bowl episode of The Late Show with Stephen Colbert, Robbie told the host and her Whiskey Tango Foxtrot costar Tina Fey that she has a tattoo gun and has given 26 tattoos. When the Suicide Squad squad was getting theirs, she added, one of the assistants on the set volunteered to go first. Unfortunately, his “skwad” is missing a letter.

Maybe Harley should reconsider opening that tattoo parler parlour.

Suicide Squad opens Aug. 5. Watch Robbie tell the “skwad” story above.
