 Congratulations to the Berkman Center on your 10th anniversary. Congratulations. Happy anniversary! Great job. And congratulations to Harvard Law School on your new way cool open access policy. Ladies and gentlemen, give me! Dum dum, beetle dum dum, beetle dum dum, beetle dum dum. There was a turtle by the name of Bert and Bert the turtle was very alert and dangerous, but until he never got hurt he knew just what to do. He ducked and covered, ducked and covered. He did what we all must learn to do. You and you and you and you and you and you ducked and covered. Be sure and remember what Bert the turtle just did, friends, because every one of us must remember to do the same thing. That's what this film is all about. Duck and cover. This is an official civil defense film. Copy that. That's a wrap.
