A substitute teacher was asked to leave early Friday after students filmed him singing, “Toxic” from Brittany Spears, poorly. It was on a karaoke machine and as you can see from the video there’s a terrible light show that went along with it. The man was let go from his duties, but sang another song quickly before that happened, students reported it was Lady Gaga. The school said he was a legit teacher he just wasn’t following standard practices. He later got another assignment at same school later that day. They really threw the book at him!
