Sideshow Bob is a recurring character on "The Simpsons". Since season three's "Black Widower" (1992), the writers have echoed the premise of Wile E. Coyote chasing the Road Runner from the 1949–1966 "Looney Tunes" cartoons by having Bob unexpectedly insert himself into Bart's life and attempt to kill him. Executive producer Al Jean has compared Bob's character to that of Wile E. Coyote, noting that both are intelligent yet always foiled by what they perceive as an inferior intellect. The scene in which Bob is stomped on by multiple elephants and bounced right back up is a reference to the Wile E. Coyote character.
