Rabbit walks into a bar and few more funny jokes

A priest, a rabbit and a minister walks into a bar.
The rabbit says, "I think I might be a typo!"

My wife said, "I can think of 14 reasons to leave you, plus your obsession with tennis."
I replied, "That's 15 love"

"Dad, I don't want to go to school today." said the boy. "Why not, son?"
"Well, one of the chickens on the school farm died last week and we had chicken soup for lunch the next day.
Then three days ago one of the pigs died and we had roast pork the next day."
"But why don't you want to go today?" "Because our English teacher died yesterday!"

Why pigs dressed in black never get killed?
Because Batman has sworn to protect goth ham.

Nicolas Desmarest

Born 16 Sep 1725; died 28 Sep 1815 at age 90.French geologist and geographer whose discovery of the volcanic origin of basalt disproved the Neptunist theory that all rocks were formed by sedimentation from primeval oceans. Studying the Auvergne of central France (1763-74), he found large basalt deposits that he traced as lava flows from nearby ancient volcanoes. He further showed that many valleys are formed by the erosion of the rivers that flow in them. From 1757, Desmarest was employed by the government to help spread better manufacturing methods throughout France. By 1788 he had risen to the post of inspector general and director of manufactures. In 1792, during the French Revolution, Desmarest was imprisoned and narrowly escaped execution.Image: Basalt rock of the Devil's Tower, Wyoming, USA, is an ancient volcanic intrusion left over after all of the overlying material has been eroded away.
