Love scene

There's a scene in Loaded Weapon when Charlie Sheen's protagonist is making love to the girl, and before they even started anything, the camera moved away to the electronic clock showing 12:10, then one minute passes, camera goes back and our heroes already smoke cigarettes. I feel that it's a spoof of lots of movies of the period, but I can't remember of which exactly. The only one I can remember of is Baby Boom (1987), but it's a comedy too and sex there takes 4 minutes, so it's certainly a spoof too. Please help!
