A Florida great-grandmother, armed with a baseball bat on Sunday taught a 300-pound burglary suspect, who police said tried to break into her car a valuable lesson: Don’t mess with grandma.

Clarese Gainey, 65, heard banging coming from outside her Gainesville home when police said she spotted 37-year-old Antonio Mosley attempting to break into her car, FOX35 Orlando reported. Mosley allegedly charged at her, but Gainey was reportedly prepared.

“I mean I popped him! I said 'Biya!' he said, 'Auuugh! You hit me!'” Gainey told the station.

Mosely then ran off in only his boxer shorts to a nearby mobile home with a gash on his head, reports said.

“I put a good one on him! But he's in jail. I ain't gotta worry about him no more. I bet you won't mess with that green goblin there, no more!” Gainey told FOX35, referring to her green car.
