Thug Notes

I recently discovered the youtube videos of “Thug Notes” where a black man gives a summary and literary analysis of classic literature using current slang popular in the urban population- and to an extent suburbia as well.  I am pretty impressed with the content and analysis but am disappointed that there is some swearing and images that may be questioned in a school context.  Another issue that some students have brought up- I teach primarily in urban settings- is the idea that people seem to think their students will only pay attention if we find a “rap” to teach a concept or other pointedly black forms of expression.  Some of my students felt this was demeaning.  I in no way think that is the idea behind these techniques- rather, we, as teachers, are struggling to keep content relevant.  So what are your thoughts- do Thug Notes hit the right notes or are they in poor taste?
