Here's a great video from PBS that features Tom Hiddleston teaching Cookie Monster a lesson about self-control. Maybe waving a cookie in front of Cookie Monster's face isn't the best way to start this lesson out. Like a true villain, Hiddleston just sits there teasing him with a cookie the whole time, but good things come to those who wait. Well... that's what I heard!
