This joke is also an elephant joke. The humor lies in the absurd reasonable of the joke. The listener assumes the the human being is talking about the ideal or the left side of the chicken, as soon as the jokester rather is talking around the inside verses the outside of the chicken, i beg your pardon aren"t really sides (even if they have actually side in their name).
