3. The Chicken Dance
http://www.youtube.com/watch?v=1TphEh0Qgv0 There is a strange, rather bewildering defect in the Bluth gene pool, in the sense that not a single member of the family is capable of doing anything even closely resembling your average "chicken impression." Which is to say, each and every time a Bluth tries to imitate a chicken (usually to insult another member of the Bluth clan), they end up doing some ridiculous twisted dance. It's GOB's "Caw! Ca-Caw! Ca-Caw!" which is become the most iconic in its failings, but not a single member of the family can muster up anything of worth in this department. "Has anyone in this family ever even seen a chicken?" Michael asks them all at one point. Doubtful.
