No matter how successful Mac Miller gets, he'll always remember where he came from -- in the most literal sense possible.

On a recent episode of "Mac Miller and the Most Dope Family," the rapper continued enjoying a visit to his hometown of Pittsburgh. And in the bonus scene, below, he shows some major love for his family during a backyard barbecue: In a pre-meal speech, Mac asks the mini-crowd to give props to his mom -- and his father's, um, genes.

"Let's get a big round of applause," Mac announces. "[My brother and I] both started out in his semen...make some noise!"

The group cheers as Mac's pop sits back and smiles, taking the compliment in stride until the rapper's friend Quentin approaches him and says, "That's some really artistic semen." Too far?

Watch dear old dad reaction in the clip, and tune in to "Mac Miller and the Most Dope Family" every Wednesday at 11:30/10:30c on MTV2!
