Skype caller Joel Kahn: exam grading and mall seed money

The show takes its first Skype call: a caller named Joel Kahn, calling from his phone, who just wanted to test Skype mobile. He explains he is heading out to grade AP math exams (cameras not allowed), and the hosts try to sell him a 3% partnership in the Million Dollar Mall for $2,000,000 plus a free wall clock. He declines and mentions Shark Tank as a better pitch venue.
