Kylie and Kendall Jenner have gone to extreme lengths to live “normal” lives.

“The only way that Kendall and Kylie will actually really get to know what it’s like to live a normal life and go unnoticed and under the radar is if they fully transform into someone else,” big sister Khloé Kardashian says in a sneak peek at Sunday’s Keeping Up with the Kardashians.

“I missed out on being normal,” says Kylie, 18. “To be able to feel like I can get out of the car and nobody is staring at me.”

“I realize that it is kind of crazy that we have to go through all of this just to go out and be normal, but it’s worth it I think – I hope,” adds Kendall, 20.

Of course, the Jenner sisters can’t have all the fun – their big sis gets in on the action, too, and hopes to be made into “an old lady.”

“I don’t want Kendall and Kylie to do this alone,” says Kardashian, 31. “I want to try this – I’m a big kid at heart, I want to have fun!”

Another clip shows the sisters getting into character as they head out for their undercover Hollywood excursion, including what they should do if they’re recognized.

Like her older sister Kim, who has been known to rock a wig and get into character, Khloé especially gets into her alter ego’s backstory: “My name’s Dolores, but you can call me Dottie,” she says. “I was born in 1937. I’m not good at math, so I have no idea how old I am, and I have two grandchildren – can’t remember their names.”

Keeping Up with the Kardashians airs Sundays (9 p.m. ET) on E!
