Prof. Mark had always wanted to do an animated music video. And much to his delight, two came up almost simultaneously. The first, "Summer Break," performed by Frankie DeCarlos, featured a bored office worker who encounters the welcome distraction of a lovely assistant. The two of them escape their humdrum office roles by literally leaping into the vacation photos on their desk calendars. (NOTE: Prof. Mark makes a cameo appearance, in animated form, as the Office Janitor.)
