He could no longer hold it back.

A drunken man armed with a slingshot was arrested Tuesday morning for urinating in front of a Haight district high school, police said.

The bumbling 35-year-old boozer was detained around 9:45 a.m. in front of The Urban School of San Francisco, located in the 1500 block of Page Street, police said.

He was booked for public drunkenness, possessing a prohibited weapon and was also wanted on a local misdemeanor warrant, police said.
