As they started, the sun became obscured by dark clouds, and as the river was large, the gentleman realised that the crossing would take some time. So he started a conversation with the boatman.
"Did you know that the sun is approximately 93,000,000miles away, and yet it has provided heat and light, throughout the universe since time immemorial, baring that, if it was to shift, even a fraction of an inch out of its orbit, there would be total devastation? "
"No sir" replied the boatman.
"Its occurrence is due to the expansion of rapidly heated air," the gentleman exclaimed, " You are 50% fool.
About ¾ of the way the weather completely changed. It became dark and started to rain heavily and started filling up the little boat with water clearly making it difficult for the boatman. But the foolish gentleman insisted in questioning.
"No sir," was the reply."
" The sun evaporates water from the sea, this gets stored in the clouds which then travel by be wind power, then when they become full, it lets all the water go, over the land. That's how we get rain."
"Oh no! I have lost my oar and now the water is about capsize the boat, we have no alternative but to swim the remainder of the way, luckily for us it is not very far."
"But I can't swim," cried the gentleman now seeing his own imminent death.
