Joke

A research team 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 structure; subsequently the second member of the team performed a self-rotational translation oriented in the same direction taken by the first team member.

It will be a while before Jack and Jill head up that hill for a pail of water again.
