Super-Memory Man

Before he was Super-Memory Man, Bob acquired other names based around the root word "Asa." "Asa" was how Bob's Pennsylvania accent rendered the phrase, "That is" or "That's" as in "Asa pretty good sketch." As a result, he became Robert Asa, Bob Asa, Bobby Asa, Bobby A, Mel Asa, and others that Bob would remember.
