I posted this list in another thread before I saw this thread but wtf anyways...
1. Christopher Walken - More cowebell baby
2. Morgan Freeman - Mississippi native and would definitely have more class than Katy Perry.
3. James Earl Jones - See no. 2.
4. Opra - Would appeal to the ladies.
Morgan Freeman might be a logical choice since our Vet School has the Morgan Freeman Equine Center and he has an endowed scholarship in the Vet School.
