These television spots for LG Mobile featuring "Actors Studio" host James Lipton really get the Funny job done. Post with background over at Laughing Squid. The campaign site is here (warning: Flash, auto-load sound). There's an article about the purpose of the campaign here.
I'm guessing they were created by the same agency that did "Subservient Chicken" for Burger King? I'm told the agency was Young and Rubicam.
Above, my favorite spot in the "Ponder" campaign, which includes a unicorn reference.
