A man walked into a restaurant...
A man walked into a restaurant and saw a sign that read, "We'll give you $300 if we're unable to serve you any entree you order."
He sat down and told the waitress he wanted elephant liver on rye.
The waitress took the order and left.
All of a sudden, the man heard terrible noises coming from the kitchen - the sound of feet stamping, screaming and the banging of pots and pans.
It went on and on.
The noise finally stopped, and the cook appeared from the kitchen.
He slapped down $300 in front of the customer and said, "I can't believe it. We're out of rye."

Meteor explosion over Chelyabinsk, RussiaIn 2013, a meteor exploded in the sky over Russia's Ural Mountains. The intense shock wave injured a reported 1,000 people, most by flying glass fragments. Many people had been at their windows viewing the meteor when the sonic boom shattered the glass panes. It was estimated to be—very approximately—65-ft (20 m) in diameter, with a mass of about 11,000 tons. It entered the Earth's atmosphere at a hypersonic speed of over 42,500 mph (68,400 kph) when it was viewed by residents of Chelyabinsk (a city of 1 million about 930 miles east of Moscow) at about 9:20 am local time, just after sunrise. They saw a thick, white contrail and an intense flash of light ending with a very loud thundering sound. The meteor blew apart with about 440 kilotons of total impact energy (as much as a large atomic bomb).« |
