And you thought, you understood English

Look at the passage, its a narration of a story we have heard thousands of times, can you identify what are we talking about here ?

Two individuals proceeded towards the apex of a natural geologic protuberance,
the purpose of their expedition being the procurement of a sample of fluid hydride of oxygen in a large vessel, the exact size of which was unspecified.
One member of the team precipitously descended, sustaining severe damage to the upper cranial portion of his anatomical structure;
subsequently the second member of the team performed a self rotational translation oriented in the same direction taken by the first team member.

So ? Any Ideas ?
Think hard I am sure you would be able to get it.
No... Then look below.












Jack and jill went up the hill
to fetch a pail of water
Jack fell down and broke his crown
and jill came tumbling after!!!
