Why did the chicken cross the road?

Issac Newton: Chickens at rest tend to stay at rest, chickens in motion tend to cross roads.

Albert Einstein: Whether the chicken crossed the road or the road crossed the chicken depends on your frame of reference.

Darwin: Chickens, over great periods of time, have been naturally selected in such a way that they are now genetically dispositioned to cross roads.

Heisenberg: Because the chicken is moving very fast, you can either observe the
chicken or you can measure its speed, but you cannot do both.

Jean Foucault:  It didn’t. The rotation of the earth made it appear to cross.

Galileo: To get a better look at the stars.

Ohm: There was more resistance on this side of the road.

Pascal: It was pressured to cross the road.

Volta: The other side had more potential.

Freud: The fact that you are at all concerned that the chicken crossed the road reveals your underlying sexual insecurity.

Grandpa: In our days, we didn't ask why the chicken crossed the road. Someone told us that the chicken had crossed the road, and that was good enough for us.
