Your dads a motherfucker.

Yeah, but he said he was drunk.

not necessarily... she may not have been a mother when he fucked her.

He used to be. My parents are divorced now. :/

Gross

That motherfucker

what a dumb shit

True but he's dead now and that brings a smile to my face

My parents were prudish. I don't think my father ever got into my grandmother. I never got into my mother either. They are all dead now.

It would have been better if I had learned more about sex while growing up.

There seems to be some confusion. "Mother fucker" usually means fucking a man's own mother, incest.
