A few months ago I acquired the DVD box set of every episode of Seinfeld, all nine seasons. Since then, I've been making my way through them one hilarious 22-minute episode at a time. It's always funny to see actors in guest spots on old television shows that later went on to become more famous. Imagine my surprise when I got to the first episode of season six, The Mango, and see that George's girlfriend is played by 27-year-old Lisa Edelstein, who now plays Dr. Lisa Cuddy on my current favorite television show, House.
I found these videos on YouTube, too.
The next two videos must be from The Masseuse, which I haven't made it to yet.
