Sid Turtlepuss is one of Earl Sinclair's WESAYSO co-workers in Dinosaurs. Apart from Roy Hess, Sid was the most frequently seen work buddy. Although Sid's surname was the most frequently used within the show (on his work jacket, during Monica DeVertebrae's hearing, or being addressed as "Mr. Turtlepuss"), in the early episode "The Golden Child," his name tag gave his surname as "Jacobs," in reference to Michael Jacobs, and his coworkers also had injoke surnames.
