Long before That ‘70s Show alum Danny Masterson was sentenced to 30 years to life in prison for raping two women, one of his fellow celebs saw through his cool guy facade long before anyone else — Conan O’Brien.

A clip from Masterson’s 2004 appearance on Late Night with Conan O'Brien began making the rounds on social media Thursday, depicting the comic slamming the sitcom star after noting his lack of a Long Island accent.

"I've been in L.A. for about 10 years and it just goes away naturally,” Masterson, who grew up in Albertson, New York, explained to the host of his relatively neutral drawl, noting that there are “always certain words you can't do anything about.”

"Like my friend, he always teases me and says, 'Hi, my name is Danny Masterson, would you like to touch my balls?'" he continued, flaunting his Long Island a-s.

Though the audience laughed at his off-handed remark, O’Brien had larger concerns with this parenthetical.

"Why are you asking people to do that? That's the more important question,” he fired back.

"I mean, you got 'em, you know what I mean?” he replied. “Everybody should grab them."

"I've heard about you,” O’Brien concluded, staring down at his cue cards, “and you'll be caught soon, I know you will."

It may have taken 16 years, but Coco’s prophecy was ultimately proven right.

So take it from Masterson: If you want someone to grab your balls, ask first.
