by : Problem $14$

 * De Bove: An ox
 * An ox ploughs a field all day.
 * How many hoofprints does he leave in the last furrow?

Solution
None.

Proof
Trick question.

As the ox walks, he pulls behind him a plough.

A plough turns over the earth as it works, thus obliterating all the hoofprints made by the ox.
