Just when you thought it was safe to go back to the 7th-inning stretch…

The New York Yankees may have acknowledged that mandatory patriotism isn’t such a hot idea, but don’t tell that to their minor-league brethren across the river:

In a lawsuit filed last week in federal court in Newark, three Millburn High School students contend Newark Bears president and co-owner Thomas Cetnar berated them, cursed at them and then booted them from the ballpark after they failed to stand for the song during the seventh-inning stretch.

“Nobody sits during the singing of “God Bless America’ in my stadium,” Cetnar bellowed during the June 29 incident, according to the suit. “Now get the (expletive) out of here.”

By “my” stadium Cetnar actually means “their” stadium: Bears and Eagles Riverfront Stadium was built and is owned by the city of Newark and Essex County. Cetnar, a former Newark police officer booted off the force after being convicted of embezzling drug buy money, has been a tenant there since buying into the bankrupt Bears franchise last fall.
