The cat is out of the bag! Jack Donaghy once belonged to the secret society Twig and Plums, while he was attending Princeton University.
Not a big shock that Mr. Donaghy would belong to such an exclusive society that only accepts the most envied men.
One story goes... while a student at Princeton, Jack and the rest of the society snuck up to Dartmouth and took their mascot, stuffed him in a box and shipped him to Mexico City. The moral of this story is don't mess with the best. Check out the top-secret Twig and Plums crest below.
