Len Lesser as Uncle Leo pretty much steals The Pledge Drive, and wow he does an impressive job chewing the screen. The Pledge Drive has Seinfeld doing a pledge for PBS and also we get a mix up with a male with a high voice and all, and it gets quite embarrassing with faux pas and all. F. J. Rio plays the Street Tough who ends up helping Seinfeld's Nana in a dark alley, as she looks for her bank. Nana is played by the late Billye Ree Wallace. I'm very much enjoying re-watching most episodes of Seinfeld, after having first watched it when it debuted in the 1990s, so wow that's over three decades ago.
