MIAMI-DADE COUNTY, Fla. – A South Florida teacher who spoke about wanting "good ass sex" on a video that was posted on the internet has been reassigned while school district officials investigate.

Local 10 News obtained the video Wednesday.

It shows Elton Lewis, who teaches language arts at Dr. Michael M. Krop Senior High School, speaking to the camera in a monologue lasting about 7 minutes and 30 seconds.

In the video, Lewis lists five things he wants for Christmas. Among the items on his wish list is "good ass sex." He also asks for a tall man with an "abnormally large penis" to perform fellatio.

Later in the video, Lewis talks about wanting to "give more Fs" to his students because it "teaches them that, sometimes, life is not easy."

"The more Fs (that) I give, the more I feel they're learning," Lewis says.

Lewis also talks about his "pent-up frustration, stress and anger from work" that makes him want to "butcher somebody."

He also speaks about giving somebody "a good blowjob."

A child can be overheard in the background while Lewis shares his graphic descriptions for the camera.

"I'm saying all of this as there's a young toddler running around me, if you can hear him," Lewis says.

Lewis sarcastically speaks about being the "savior of the youth of America," saying he became a teacher so he can say "inappropriate things around little toddlers."

"The school's principal was recently alerted about the presence of a video that was allegedly posted on the internet by one of our teachers," Miami-Dade County Public Schools spokesman John Schuster said in a statement. "The video contains content and language that is extremely inappropriate. Miami-Dade County Public Schools holds its employees to the highest moral and ethical standards. As such, this employee has been reassigned away from the school while the case is being investigated."
