The latest ads in Carmichael Lynch's master and apprentice campaign for Steak 'n Shake continue to use sound effects and choice props to comic effect.This time, the main featured sound effect is the comically exaggerated air karate chop. The latest series of wooshes reminds us fondly of Weird Al's absurd dance sequence in his 1988 parody of Michael Jackson's Bad ("Because I'm fat ..."). As for the prop, it's a black blindfold that the master wears in his Pin-the-tail-on-the-donkey-like search for a milkshake in the desert. The tagline remains, "Hunger wisely."As with last year's spots, these were directed by Harold Einstein.
