Random Factoid...drop your cookies when done cooking?

I was just reading on the Freeze Happy web site- which is awesome, she gives all of these recipes that are great to make ahead and freeze- and she gave a recipes for chocolate chip cookies and she had a suggestion for when you are done cooking them and right out of the oven, she suggested, "As soon as you remove them from the oven, hold the cookie sheet 4 inches above the floor and drop the sheet. This releases excess air in the cookies and makes them more moist and chewy." She said that she worked at a bakery and that is what they did. That is so funny. I almost laughed out loud when I read that because I just pictured myself dropping cookies on the floor on purpose, not on accident- I have been dropping everything lately it seems.
Hope you all have a nice weekend- Laura
