Sixth-Grade Teacher Goes On Very Inappropriate Rant During Class [Video]

A sixth-grade teacher in Dallas got into some trouble after he went on a profanity-filled rant in one of his classes.

The teacher wasn't named, but a 12-year-old student recorded the entire seven-minute tirade at Holmes Middle School.

The teacher has since been placed on administrative leave while the school investigates, KTVT-TV CBS Dallas-Fort Worth reported.

During his rant, the teacher talked about the students "not giv(ing) a (f**k)," and then bragged about the size of his crank.
