The city just got hit with one heck of an ice-cream headache.

Some of Good Humor’s most popular ice-cream bars are in short supply on trucks throughout the area.

“We’re really not sure why this is happening,” said Nassau County Legislator David Denenberg, surrounded by kids. “Today, I scream, you scream, we all scream for a lack of ice cream!”

Parent company Unilever blamed a factory closure for the shortage, which includes the chocolate eclair (inset).
