In a parallel universe giraffes developed long necks specifically for the purpose of snatching small children from over short fences, in order to devour them whole. It is therefore necessary, in this universe, to build giraffe-proof fences around all townships. This fence is dangerously short, probably accounting for the lack of small children in view.&nbsp;[Giraffe&nbsp;in Cairo zoo], glass lantern slide, ca. 1915-1918, by&nbsp;T. P. Bennett.
