Kim Kardashian revealed that she cut a joke from her infamous "Saturday Night Live" monologue. So what was the joke in question?

The reality star made headlines when her ruthless roast spared none, aiming at everyone from Kanye West and her famous sisters to O.J. Simpson. Recently, audiences found that there was one joke Kim thought went too far.

In episode two of Hulu's "The Kardashians," Kim is seen running jokes by comedian and friend Amy Schumer ahead of her hosting gig. She recites,

"Oh, Khloe, you have the biggest heart. It's so big, it has room for Tristan and all of his side pieces."

Schumer reacts with, "Oh s**t," the moment she hears it. It isn't revealed why Kim cut the joke in the end, but at the time of taping, Khloe and Tristan were "not together, but on amicable terms."

This was around the time several public scandals broke that revealed Tristan cheated on Khloe multiple times. The pro athlete was the subject of a paternity lawsuit that revealed he fathered a child with Maralee Nichols.

Meanwhile, Khloe attended Kim's SNL taping to support her sister, even making an appearance in two sketches. In episode one of "The Kardashians," Khloe says about Tristan,

"Tristan and I currently are not exactly together. He's one of my best friends. I see Tristan a couple times a week. He's a really hands-on dad. Me and Tristan don't have tension. He's a really hands-on dad... I know if Tristan had his way, I guess, then we would completely be together. I just need a little breathing room and time to think."

The two had been attending counseling while co-parenting their daughter together, with Tristan continuing to push for a romantic future with Khloe. She says,

"Him and I have been through so much together that I have a lot of reservations. My guards are up."

New episodes of "The Kardashians" stream on Hulu every Thursday.
