Kendall Jenner Jokingly Dressed Up as Kylie in a Pink Wig

And, of course a Kylie lip kit!

Trolling your younger sister is a rite of passage that never gets old. Just ask Kendall Jenner and Kylie Jenner.

In a teaser clip for the season finale of Keeping Up With The Kardashians, Kendall Jenner dressed up and put on her best Kylie Jenner impersonation which included a colorful wig and a dramatized application of Kylie's iconic lip kits.

In doing so, she even cracked up the cameraman. (And, naturally, she cracked us up too! We want more of this please!)

All in good fun, Kendall even FaceTimed her little sis from a family dinner to show off the new lewk saying, "I’m Kylie!"

And Kylie approved. "You look cute as Kylie," she replied, adding, "It looks amazing!"

In the teaser, Kendall also poked fun at Kylie's lip-swatching technique, showing off the painted swatch marks on her inner arm and saying in a Kylie tone, "this is what it looks like..."

And, it seems she wasn't the only one playing dress-up. In the quick clip, you can see momager Kris to the right rocking a long, bleach blonde wig, too. Is she impersonating Khloe or Kim? What the heck kind of dinner was this? We need to know, stat.

The Keeping Up With The Kardashians season finale airs this Sunday at 9|8c on E!
