Calm down, dude!

A Teenage Mutant Ninja Turtle lost his cool with a photographer near Times Square and cops had to break up the argument.

A woman who didn’t want to be named was taking pictures of four of the costumed turtles as they talked to police while panhandling during a street fair on Sixth Avenue near 49th Street at around 3:40 p.m Sunday.

When she took a photo of Michelangelo posing with a passer-by while accepting money, he pulled off the head of his costume and confronted her.

“You have to stop that,” the turtle whined. “We work for money.”

When she informed him she can take pictures in public, the character — who was 6-feet tall and armed with nunchucks on his hip — said, “Don’t harass me.”

“At the point I was very frightened,” the woman said.

Officers restrained the man but did not arrest him.
