We all have had a Bad Teacher now and then especially those substitute teachers. But who could be badder teaches than these folks?

Bad Teacher premiered at the Ziegfeld Theatre in New York City last night, and stars Cameron Diaz, Justin Timberlake, Jason Segel, Lucy Punch and additional cast members were in attendance. Here are some photos we obtained from the gala. Bad Teacher is out as part of the Summer Movie happenings in theaters nationwide this Friday, June 24th!
