I'm beginning to like this new class of students, though. Less of a professional actor/actress air about them, and more of the competitive game show contestant spirit. Or game show lifeline spirit, as it happens to be here. When they get questions right and walk back to their desks, they share a high five with each other.
In particular, Nathan has been cultivating the title of "The Closer"; he likes being called last, so he can help out a contestant for the big money questions. Last night he helped Tony out twice, with the Save and then the Copy, getting $175,000 for Tony's foundation. Tony promised to name a skateboard park in Nathan's honor. (Actually, since he promised that after the $100K level, I think he owes Nathan two parks!) And, at the end of the show, Tony took the skateboard he had entered on and handed it to Nathan, autographing it for him. Finally, a tip!

WTG, Nathan!
