Zonker: Michael, I can't tell you how delighted I was to discover Walden puddle! Right here on our own property! You know, I'll bet I'm the first human-type to lay eyes on that puddle! What a puddle! Wet and wild, and unpolluted to boot! Man, I felt like Magellan, or Cortes, even. Mike: C'mon Zonker. A puddle's a puddle. Zonker: Well, you can say that, of course, but I'm sure of one thing about Walden....it's not your run-of-the-mill puddle.
