With news being slow on the weekends, a few weeks ago I started a column called PSA Sunday. As you can probably deduce from the title, every Sunday we post a PSA featuring TV or movie characters and/or a celebrity telling you not to do something. The first few weeks focused on vintage Star Wars PSAâs (the Cantina aliens in a âFriends donât let friends drive drunkâ campaign, C3P0 and R2D2 talking about the dangers of whooping cough, and C3PO and R2D2 warning you about smoking) as well as a Transformers PSA from the 80â²s that featured Bumblebee talking to kids about running away from home.For this weekend's PSA, we've got Clint Eastwood telling you not to do crack cocaine. Hit the jump to check it out.
