The man, Jared Largo, said he was just trying to spread Irish cheer ahead of today's St. Patrick's Day festivities. The rubber stamps, using a black ink pad, were about three inches wide, in the shape of an Irish clover.
Largo, who is a mate on the ferry and sometimes steers the boat, stamped the area around the ferry's wheel house, as well as near the time clock where employees check in for duty.
"I looked at it as the same thing as Christmas decorations," he told The New York Times. He said he'd planned to wash off the stamps after the holiday.
That wasn't acceptable to his bosses at New York's transportation department, who captured what they considered Largo's vandalism on video and summoned him to appear before an internal judge. At the hearing, Largo wore green shoes.
"The judge was like, 'What, you think you're funny, wearing green shoes here?' " he said.
Largo was suspended without pay for 16 days. The hearing took place last month, and his sentence runs through next week.
As for how he's spending his free time off work, Largo -- who is half-Irish -- told the Times he plans to attend New York City's St. Patrick's Day parade today.
"I was thinking of renting a green tux," he said.
Until next time..... Lorie
