A man and his wife were drivin

A man and his wife were driving their RV across the country and were nearing a town spelled Kissimee. They noted the strange spelling and tried to figure how to pronounce it - KISS-a-me; kis-A-me; kis-a-ME. They grew more perplexed as they drove into the town.
Since they were hungry, they pulled into a place to get something to eat. At the counter, the man said to the waitress: "My wife and I can't seem to be able to figure out how to pronounce this place. Will you tell me where we are and say it very slowly so that I can understand."
The waitress looked at him and said: "Buuurrrgerrr Kiiiinnnng."

Krypton

In 1898, Morris William Travers, an English chemist, while working with Sir Willam Ramsay in London, discovered the element krypton. The name derives from the Greek word for “hidden.” It was a fraction separated from liquified air, which when placed in a Plücker tube connected to an induction coil yielded a spectrum with a bright yellow line with a greener tint than the known helium line and a brilliant green line that corresponded to nothing seen before.
