Friends — "The One with the Thanksgiving Flashbacks"
Friends mastered the art of the flashback with numerous trips into the past, but the most memorable trip down memory lane involved Chandler's Flock of Seagulls haircut, Monica's fat suit and a poorly placed steak knife. Oh, and did we mention Rachel, pre-nose job? They may have looked different, but they were still our quirky, lovable Friends.
