In Rocky Horror, Brad and Janet go driving off "one late November evening." Let's say around 8:30pm. They have a "blowout" and walk "back down the road a few miles" in heavy rain. Now it's around 10pm, and the last of the trannies have all pulled up their motorcycles, dried off, and are dancing the Time Warp.

Then Frank meets Brad and Janet, makes a speech, and Rocky is created. I figure it's 11 at the earliest, by now. Frank retires with Rocky, then Wonder-Fucks Janet, then Wonder-Fucks Brad, then Janet does Rocky. Later, after Dr. Scott shows up, they are discovered sleeping under a sheet. Then, everybody has "dinner". What time is it? What meal are they eating? I put it to you it's like 2am, and they are having the grandmother of all Rocky restaurant outings, a late-night event which we have followed quasi-religiously ever since.
