As if Lil Wayne needed more legal hassles, a Manhattan federal court suit says the prison-bound rapper and label mate Birdman used a Florida man’s voice without permission on Mafia-theme song intros for their “Like Father, Like Son” and “Birdman 5* Stunna” CDs.

Thomas Marasciullo claims the rappers and Cash Money Records asked him in 2006 to say into a mike such goombahesque utterances as “If you’re with us, you’re with us” and “Family is a big thing.” They then used the recordings without compensating him, the suit says.

Marasciullo, who had met the rappers through his recording-engineer son, Fabian, said he realized he’d been ripped off when his daughter, seeking an Aretha Franklin “R-e-s-p-e-c-t” ring tone, got “Respect” from Birdman’s “Like Father, Like Son” — with her dad’s voice on it.

Neither rapper’s lawyer returned calls for comment.

Next February, Lil Wayne is to be sentenced to a year in prison for gun possession.
