The video involved a girl practicing her best twerking skills for her boyfriend, which ends terribly -- her roommate enters the room, knocks her over onto a glass coffee table.
Of course, there are also lit candles on the coffee table, which light the girl's yoga pants on fire.
The video, “Worst Twerk Fail EVER - Girl Catches Fire!,” was a big hit on YouTube, racking up more than 9 million views. It also showed up in local TV news shows across the country, along with national ones like "The View" -- all of which were unaware they were being pranked.
On his show Tuesday, Kimmel introduced the girl from the video, "Caitlin," through a supposed Skype interview from Kansas City, Mo., on the show. During the interview, Kimmel went behind the curtain and sat next to the girl, where he got her to tell everyone the truth: "Caitlin" is actually professional stunt performer Daphne Avalon.
