Here we have the guy from Saturday Night Live.  His two career highlights were "Lazy Sunday" and "Ras Trent".  His Ras Trent character is a white rasta.  They took the video off of YouTube but I guess it's on the SNL website.  Here's a funny Bob Marley cartoon instead:  http://www.youtube.com/watch?v=WSQvc6VWrPY

Here's Ras Trent's other famous video:  http://www.youtube.com/watch?v=TuXhGLveY7o

And, no, I don't really think that Bob Marley was a poseur!
