Things were tense, as each 1D guy and James chose a box. Four of the boxes said "safe" inside and one had the word "tattoo." The lucky fella with "tattoo" had to get inked right then and there.
Niall was understandably nervous, as James noted, "Your hands are actually shaking." Niall joked: "It's my first time on TV."
While Harry Styles said he was fine with it, Louis Tomlinson chalked it up to being "another stupid [ink]" to join his collection.
One person who wasn't too thrilled? Harry's mom, who tweeted: "@JKCorden we need words young man."Uh-oh, James!
