Well, I don't know if anyone doesn't know this, or cares, once again, but I found it quite interesting, in light of the cute Midnight Cowboy tribute that Seinfeld did. I happened to watch Midnight Cowboy - never saw it before in its entirety.
Bob Balaban has a small role in it and he looks to be in his early teens. Only when I read the credits at the end did I realize it was him. It's not listed among his roles in my TV-Movie video guides. (He's also more recently in Deconstructing Harry along with Julia).
