Bob is an animated man designed by Cliff Roberts, with a red nose who wears a derby and a bow tie. He introduced each episode of Sesame Street that appears on Old School Volume 1. In his introductions, he starts to talk about the show, and slowly starts talking about himself before an off-camera voice tells him to start the show. His design is very similar to that of a character used in the 1969 "Poverty X" animation.
