There are many riddles that assume a familiarity with this well-known riddle and its answer. For example, an alternate punchline can be used for the riddle, such as "it was too far to walk around". One class of variations enlists a creature other than the chicken to cross the road, in order to refer back to the original riddle. For example, a duck (or turkey) crosses "because it was the chicken's day off", and a dinosaur crosses "because chickens didn't exist yet". Some variants are both puns and references to the original, such as "Why did the duck cross the road? To prove he's no
chicken". Other variations replace
side with another word often to form a pun. Some examples are: "Why did the chicken cross the road? To get to the idiot's house....
Knock-knock." ("Who's there?") "The chicken." "Why did the chicken cross the playground? To get to the other slide." "Why did the
chewing gum cross the road? It was stuck to the chicken's foot." "Why did the whale cross the ocean? To get to the other tide." "Why did the dinosaur cross the road? Chickens didn't exist yet." "Why did
Darth Vader cross the road? To get to the Dark Side." "Why did the chicken cross the
Möbius strip? To get to the same side." "Why did the
toys cross the road? To get to the chicken on the other side." As with the
lightbulb joke, variants on these themes are widespread. == References ==
