We’ve seen some great Britney Spears spoofs in the past, but young Sally Draper’s will drive you crazy.

Kiernan Shipka, aka Sally Draper from “Mad Men,” visited Jimmy Kimmel on Wednesday, and the two revealed Shipka actually got her start on the late night show. One old segment in particular shows the actress as a Elissa Webber, a student in Britney Spears’ dance class. Unfortunately, it looks like she’s picking up a little more than dancing.

Sally Draper has gone through some traumatic moments on “Mad Men,” but they don’t come close to this.

“Jimmy Kimmel Live” airs weeknights at 11:35 p.m. ET on ABC.
