Security officers at a New York airport found themselves facing a nutty situation this holiday season: gun parts buried in jars of sticky peanut butter.

The discovery at John F. Kennedy International Airport came Dec. 22, when a checked bag triggered an alarm during the screening process. A Transportation Security Administration officer removed two jars of Jif peanut butter from the luggage and found parts of a disassembled .22 caliber handgun — including a loaded magazine — wrapped in plastic and hidden inside, the agency said.
