In a lot of the episodes (especially the first half or so of all aired) there is a one frame faint screen of text right after the last video of each episode (and before the end credits). This entire screen of faint text is usually a rant from the makers of the show against VH-1 about what they couldn't put into the pop-up bubbles for the videos of that episode.
The credits are presented in the pop up bubbles that make up the show.
