This is soo cool.

Lindsay Lohan is probably a better neighbor than this man, and that's really saying something!

A Pennsylvania man accidentally fired a 2-pound cannonball into his neighbor's house!

What the hell?!

William Maser, 54, is a history buff with a dangerous hobby. He has been recreating 19th century cannons and then firing them off for years!

The cannonball, 2 inches in diameter, unexpectedly ricocheted and went through the neighbor's window AND wall before landing in a closet.

Luckily, nobody was hurt because of this guy's stoopidity!

Maser was charged by the Pennsylvania state police with reckless endangerment, criminal mischief and disorderly conduct.

He has since apologized and agreed to stop shooting cannons on the property.

Uh yeah, we think that's best.

Idiot!
