If only we thought of this! Kim Kardashian appeared on Ellen DeGeneres’ new YouTube series, the Show Me More Show, and revealed that she used to cheat on all her tests in high school — and she had a very clever way of doing it.

Asked to share a secret she kept from her parents in high school, Kim, 36, said, “I used to cheat on all of my tests. We’d wear uniforms, so I’d wear this little skirt. I’d flip up the skirt and write all of the answers in, like, washable ink. And, like, what is the teacher going to do? Ask you to lift up your skirt? Like, sexual harassment.” To learn more, watch he video below!

During her time in the hot seat on the Show Me More Show, the KKW Beauty mogul also revealed some other interesting tidbits. According to Kim, her favorite body part is her “upper stomach, if that’s even a thing,” her first celebrity crush was Johnny Depp, and her husband, Kanye West, has a better “natural” fashion sense than she does.

The best part, though? When Kim nailed a spot-on-impression of her notoriously monotone older sister, Kourtney Kardashian. “She’s just like, ‘Yeeeahh,’” the Selfish author said in the mom-of-three’s signature voice. “‘OK? Yeeeahh. Yeeahh.’”
