Good morning.

Things have been a bit busy already today. Our early headlines:

-- Unemployment Rate Dips To 9 Percent; 80,000 Jobs Added.

-- Corzine Resigns From MF Global.

Jon Corzine, the former governor and senator from New Jersey, has resigned from his post as head of MF Global. The company has been under scrutiny from regulators and investigators following its rapid decline and bankruptcy filing earlier this week.

The nation's unemployment rate ticked down to 9 percent in October from 9.1 percent in September, the Bureau of Labor Statistics just reported.

Meanwhile, there was a net gain of 80,000 jobs on public and private payrolls. Private-sector employment went up by 104,000 jobs. Government agencies reduced their payrolls by 20,000.

We'll have more from the report shortly.

The most-anticipated economic news of the week — word about the October unemployment rate and, hopefully, how many jobs were added to payrolls last month — is due at 8:30 a.m. ET.

The butcher shop R.J. Balson and Son began selling sausages and bacon in 1535 when Henry VIII was king and still married to Anne Boleyn. Twenty-five generations later, owner Richard Balson tells the Daily Mail his son will join the business next year — and that son has a son too.

A cleaning woman working at the Ostwall Museum in Berlin noticed a wet stain on the floor by a modern-art sculpture. She scrubbed away the stain, not realizing it was part of the piece called, "When It Starts Dripping From the Ceiling." Back in 1986, another cleaner in Germany wiped away a grease stain valued at 400,000 euros.

It felt like 2008 all over again in Philadelphia this week. A DJ played a song by the Black Eyed Peas to warm up a crowd of about 500 students from local colleges. President Obama's campaign manager, Jim Messina, exhorted the crowd at the University of Pennsylvania to volunteer, to apply for internships and, of course, to vote.

"There's 8 million registered voters who are 18 to 21 who weren't old enough to vote last time, who are going to cast their first vote, and they're going to do it for Barack Obama," Messina said. "Raise your hand if you're 18 to 21!"
