The Bueller commercial needed more than Ben Stein to save it. It needed the real Cameron on the roller coaster (not some schmuck in a Red Wings jersey), and the Sausage King of Chicago. Either of those guys show up and this commercial becomes worthwhile.
I don’t know. I think the idea of Leno popping in at the last minute to steal something that someone else worked hard for and desired greatly is pretty funny. Just doesn’t seem like something he would do.
