Bank Teller

This guy walks into a bank and says to the teller at the window, "I want to open a freakin' checking account."
To which the lady replied, "I beg your pardon, what did you say?"
"Listen up dammit, I said I want to open a freakin' checking account right now."
"Sir, I'm sorry but we do not tolerate that kind of language in this bank!" The teller left the window and went over to the bank manager and told him about her situation.
They both returned and the manager asked, "What seems to be the problem here?"
"There's no damn problem," the man says, "I just won $50 million in the lottery and I want to open a freakin checking account in this damn bank!"
"I see sir," the manager said, "and this bitch is giving you a hard time?"

Aluminium process patent

In 1889, Charles M. Hall patented an inexpensive electrolytic process to extract aluminium from its ore (No. 400,655) which he had invented on 23 Feb 1886. Although aluminum is the most abundant metal in the earth's crust, it is not found naturally in pure form, and thus it must be separated from its surrounding ore.
