(NYDAILYNEWS) — A high school math teacher known for his volcanic temper was yanked from his Queens classroom after a video caught him spewing spit into a student’s face.

Expectorating educator David Pecoraro — labeled a serial spitter by students — was caught screaming at the unidentified Beach Channel High School kid just seconds before the saliva sailed.

Students said the pair fought over the youth’s cell phone before Pecoraro, an outspoken critic of Mayor Bloomberg’s education reforms, turned spitting mad.

“You want to go to jail now?” asked Pecoraro, who earns $100,049 a year, after the pushing match. “You’re gonna go to jail.”

“What the hell are you doing here?” the student shot back.
