I like Alton Brown, despite his liberal use of "ah's" in his monologues, but today I saw him teaching people to chop by moving the food toward the knife (I always move the knife). How do YOU do it?
Then he pulverized a poor garlic clove with a cube of marble! Ghastly scene - I made my child look away. I hate it when he overcomplicates things, especially with a single-function tool.
