He's making violent love to me mother!

Ha ha... no, probably no more than necking, if even that, but that line always cracks me up. Also, the mother doesn't even gasp and come running down the stairs. She just tells Mary to send him home. Funny!

This was always my favorite line, the delivery just makes it great.

Eh, I'm no hero. I just like to hit people on the head

Ah, back in those days to make love to a woman meant to court her (basically wooing with words ONLY).

By the 1950s or 60s it meant a tiny bit more - so yes, wooing and kissing. In fact there's a Marilyn Monroe film called Let's Make Love. (And no, just because its MM dont think the phrase meant something more explicit, such as *bed creaking noises*. The French male lead, whose name I cant recall right, spoke several languages but still could not tell her how he felt....

Gracie Allen on the Burns & Allen Show used to tell young people they should be making love all the time. She meant kissing/making out.

To add to the other replies, another example is in *Rebecca*, when Maxim de Winter says to his new fiancée, "This isn't at all your idea of a proposal, is it? It should be in a conservatory, you in a white frock, with a red rose in your hand, and a violin playing in the distance, and I should be making violent love to you behind a palm tree."
