• Chuck the Wonder Dog : [Barking while running along the creek, holding Irwin's underwear in his mouth] 

  Bob McGraw : Hey! It's Chuck! Hey, Chucker!

  Chuck the Wonder Dog : [Whines, barks, and rolls around on the bank of the creek] 

  Max : Bob, it looks like he's been drinking again...

  Gonzer : No, no, no, no, no... not drinking, look in his mouth! It's Irwin's underwear!

  Max : Oh, well then no wonder he's acting like that.
