LOL! IT WAS A GUN BUYBACK NOT A GRENADE BUYBACK STUPID!

It was a gun buyback, not a bomb buyback.

A dimwit was being held by police Saturday after he attempted to turn over a live hand grenade to police at a gun-buyback program in the Bronx.

Police evacuated the New Gospel Temple Church of God in Christ and surrounding buildings around 1:30 p.m. after the unidentified man waltzed in with an improvised hand grenade, officials said.

The NYPD's Bomb Squad unit arrived at the E. 173rd St. church wearing protective gear around 4:30 p.m. and left 15 minutes later with the grenade, carting it out in a special carrier.

Police were questioning the man Saturday night, but a law enforcement source said it was unlikely he would be charged with any crime.

The program, which offers $200 for guns - no questions asked - had kicked off Saturday across the borough, a spokesman for the Bronx district attorney's office said.
