What is up with the kids at Penn State on Wednesday's "Mad Money" show? Why did they pitch stocks that Cramer has already been all over for a long time like Allergen (AGN), Nike (NKE) and Raytheon (RTN)? The students at Indiana University gave us names like Spartan Motor (SPAR) that we hadn't had before, and these guys bring a bunch of stuff Cramer has discussed regularly. Sorry, but they didn't come to play.
