YOU'RE KILLIN' ME, SMALLS TMZ.com
"Sandlot" star Tom Guiry, who played Smalls in the movie, got busted for throwing a strike ... but cops say he didn't hit his target with a baseball, he used a dumbbell!!!
TMZ obtained video of the alleged incident ... and it appears to show Tom tossing a huge weight on a car windshield, shattering it completely.
The footage is absolutely bonkers ... you see Tom bring the dumbbell behind his head and then drop it on a white Jeep .
