Actor Allusion/Music Videos

The Reba McEntire music video "Every Other Weekend" features a divorced couple played by JoAnna Garcia and Steve Howey, who played Reba's daughter Cheyenne and her husband Van on her sitcom.
David Bowie's Hard Rock group Tin Machine made a video for "You Belong in Rock and Roll" in which, among other things, Bowie poses in front of a mirror. At one point, he brings a pair of tweezers up to his eye, as if he were about to pluck something from it. This references an important scene in The Man Who Fell to Earth, in which it turned out that his character was removing something -- namely, the contact lenses that disguised his alien eyes.
The Great Luke Ski spends an entire verse of One Night In Quarks Bar making one reference to Principle Snyder, Armin Shimmerman's character in the Buffy the Vampire Slayer.
