When Tony and LaDonna Land discovered naked carnival worker Gregory Matthew Bruni on their roof, that alone could've made news. But their night had just begun.

Bruni, 21, allegedly assaulted Tony Land, trashed the couple's North Fort Myers, Fla., home and then defecated and masturbated INSIDE the house.

The Lands told police they were in their bedroom at around 7 p.m. Monday when they heard a noise that sounded like thunder, according to Fox 4 Now.

Tony went outside and says he saw Bruni on top of the roof, naked. Bruni allegedly jumped down on top of Land, knocking him over by hitting him in the shoulder.

The Lands say Gregory Matthew Bruni ran into the house, pulled a big-screen TV off the wall, and spilled the contents of a vacuum onto the floor.

LaDonna then grabbed her gun and began firing at the nude intruder.

She missed, and the couple called 911 ... as the situation got weirder.

After shots were fired, Bruni began masturbating feverishly in their living room before heading into their son's bedroom to rub some clothing on his face.

He also defecated on the floor in two spots within the home ... and sucked up the contents of the vacuum he had just emptied, then spit them back out.

The whole thing has a zombie apocalypse feel to it ... sans flesh-eating.

Authorities arrived, restrained the intruder, took him into custody and transported him to a hospital for evaluation. That should be one serious evaluation.

Bruni has been charged with criminal mischief, battery, occupied burglary and resisting arrest without violence. That's what happens when you ...

Get naked and climb up on someone's roof.

Jump off the roof onto someone and injure them.

Knock down somebody's flat screen TV.

Masturbate in someone's living room.

Defecate on the floor in two places.

While dodging bullets and drinking vacuum cleaner contents no less!

All in a day's work ...
