Commando Teacher Does A Cartwheel, Flashes Her Vagina To The Entire Class

A substitute teacher in Oklahoma says she was just "trying to be a cool teacher" when she did a cartwheel for the kids.

Well, she was cool alright -- probably from that breeze up her dress because she didn't have on any underwear! That commando cartwheel landed 34-year-old Lacey Sponsler in jail with an indecent exposure charge.

Cops say she tried to deny it even happened, but a student at Pawhuska High School caught in all on cell phone video, forcing the police department to send out this Facebook message:

It gets worse.

According to The Smoking Gun, a student told cops along with "exposing her bare vagina" and seeing it "open and close," Ms. Sponsler "had been talking about using drugs" and said she "thought 14-year-old boys were like men."

Turns out, Sponsler's also pleaded guilty in the past to drug possession and public intoxication.

Uh... what happened to background checks?!
