It's trash. It's not really useful to us. // later, conclusions about a different, more interesting divergent series Kirk: It's trash. ...

//Stein is handing back a test on Infinite Series. Neel gets 100 (Meow!). Student: I didn't get the telescoping one... Neel: There was a telescoping series? I didn't notice. [Stein snatches Neel's test out of his hand.] I probably shouldn't have said that out loud... [Neel gets his test back with a score of 95.] Neel: -headdesk- //Later that class, Neel is tearing up his test. Stein (to Neel): What are you tearing up? ... Was that your test? [Neel nods] You have a final exam coming up in this class. You're going to need that to study. Why would you do that? Neel: To destroy evidence of my failings... Stein: What, did you get other stuff wrong? Neel: I dunno, I didn't look at it.
