Michael Rotondo finally left his parents’ nest Friday, but not before delivering one last parting shot at them — by siccing the cops on his dad over some missing Legos.

The infamous 30-year-old freeloader — whose parents won a court order to evict him from their suburban Syracuse house — called 911 reporting that his dad, Mark, wouldn’t let him into the home’s basement to search for his 8-year-old son’s Legos.

The 61-year-old father offered to look for the toys and other items Rotondo wanted to take with him, but the layabout still whined like a baby.

“This isn’t a game show,” he told Syracuse.com. “I don’t have to guess what’s behind Door No. 1.”

The cops showed up, the Legos were found, and Rotondo finally vamoosed at around 9:30 a.m. — a whole 2¹/₂ hours ahead of his court-ordered eviction deadline.

Rotondo said he had “more or less” bid goodbye to his parents, who were at the Camillus home.

He then left in his aging gray Volkswagen Passat station wagon — but needed a jump before he could even pull out of the driveway.

“I gotta get going before that thing blows up,” he said, explaining the jalopy was running without coolant.

Driving past reporters, Rotondo beeped the horn and waved.

But he isn’t going far.

The notorious moocher says that he will be using the $3,000 he got for appearing on conspiracy theorist Alex Jones’ show to stay at an Airbnb rental for a week, but that he will then move in with his distant cousin Anthony Mastropool — who lives a just block from Rotondo’s parents’ house.

It was unclear how long that arrangement would last.

“I don’t mind if he stays here a few days, but something permanent, I’m not sure . . . It’s in discussion,” Mastropool’s fiancée, Janise Goode, told The Post Friday. “I’m about to be married next year, and I don’t know, I’m just too old for roommates.”

Last month, parents Mark and Christina Rotondo sued to evict their unemployed son. Michael Rotondo asked for six more months at home, but a judge shot him down.
