Man sold laughing-gas filled balloons: cops

Who’s laughing now?

A man tried to sell balloons filled with laughing gas to a cop outside a Disco Biscuits concert at Irving Plaza, police said on Wednesday.

Carlos Holguin set up shop on East 15th Street near Irving Place with a nitrous oxide tank — selling the balloons to patrons showing up for the show at the Gramercy Park-area concert hall, according to cops.

Sources said the laughing-gas vendor made his alleged error after the show by the popular Philadelphia band at around 2:15 a.m. on June 13.

That, police said, was when Holguin was spotted filling up a balloon and offering a cop on patrol his wares — allegedly even giving the officer a rocking sweet deal on the good-time balloons.

“Four for $20?” he asked the officer, sources said.

The cop, apparently uninterested, cuffed him.

Holguin was charged with unlawful use of nitrous oxide for intoxication and unlicensed general vending, cops said. Both are misdemeanors.
