The massive Occupy Wall Street march brought out the best, the worst and even the funniest in New Yorkers as protesters and police squared off yesterday.

A group of wrong-way protesters intent on storming City Hall ran instead to the Board of Education building on Chambers Street, where they drew laughs as they chanted, “Bloomberg Must Go! Bloomberg Must Go!”

One of the clueless crew eventually realized the mistake, telling his pals, “This isn’t City Hall.”

Undaunted, the group picked up and ran to equally incorrect One Centre Street — with one exclaiming, “There it is! That’s City Hall!” — and the chanting resumed.

Cops and Occupy Wall Street protesters agreed on at least one thing — more cowbell!

As one particularly enthusiastic member of the 99 percent was strolling down Broadway in the East Village loudly clanging a cowbell to rally the troops, a uniformed cop spotted the unusual instrument and burst into smile.

“More cowbell!” the officer yelled to the bell-ringer, referring to the popular “Saturday Night Live” skit with Christopher Walken.

Even top NYPD brass weren’t afraid of mixing it up with the masses.

NYPD Chief of Department Joseph Esposito, the city’s highest-ranking uniformed officer, went face to face with protesters near the Stock Exchange.

At one point, Esposito held a demonstrator by the throat while he exchanged heated words with another.

Rep. Michael Grimm has had it up to here with grime.

“Buy a bar of soap, and head home,” the freshman Republican from Staten Island snapped at the Occupy Wall Street crowd. He called the protesters a bunch of “lowlifes.”

Don’t mess with a protester and her right to wave around an outdoor flag in a crowded ferry terminal!

Occupy Wall Street supporter Nana Chilton flipped out when police told her she couldn’t bring the banner into the Staten Island Ferry Terminal in St. George.

“I’m an American! Get your hands off my flag!” she yelled at officers. She finally calmed down when cops said they’d let her in with the flag if she left the pole outside.

“I had to hold myself back,” said Chilton, adding ominously, “Don’t touch someone who knows martial arts.”

Even lovable Muppets were fair game for cops trying to break up demonstrators.

As chaos erupted around him, a protester dressed in a Cookie Monster costume held up a sign that read: “99 percent of the cookies are eaten by the 1 percent!”

When he was roughed up by police, witness Melissa Shaw noted, “That was really awful.”
