There's a really cute M&M's commercial for their new M&M's Dark Chocolate that's airing now.
The commercial is in black-and-white instead of color, and starts off with the theme music from The Addams Family tv show. It's a parody of the opening sequence from that show, with the main characters (Gomez, Morticia, Uncle Fester, Lurch, etc) drawn in the shape of M&M's and the two M&M's (yellow and red) inserted into the sequence with typical Addams Family features (Uncle Fester eyes, etc). Then the voiceover introduces the new Dark Chocolate M&M's as the sequence ends.
Very clever and cute.
Here's the commercial, from the official M&M's site.
