Pretty much the last Reggie Watts video out there that's worth sifting and not already sifted. In this one, he raps about his scrotum-tugging robot, Scrotor.
Reggie's act is jaw-dropping and he is much more prolific than this modest web presence attests. When I was in New York, I saw him about 8 times, and he was the only comedian that never repeated himself. He has to go last because he always tears the place down.
