Getting your music video played on MTV was the goal of almost every musical act in the 1980s and 1990s. (Yes, kids: MTV actually used to play music videos instead of a 24/7 loop of Real World/Road Rules Challenge). And there was nothing to make your music video stand out like have a celebrity - or multiple celebrities - show up for a cameo.

Who could deny the celebrity firepower of Rodney Dangerfield, Milton Berle or Ally Sheedy? One of them appearing in your music video = instant hit! We break down the best - and strangest - celebrity music video cameos ever. Jeff's had enough of Michael and Richard's shenanigans, so he's brought in some help - his brother Sam!

It's double the Hopkins, double the judgments.
