Shaggy & Scooby-Doo Get a Clue! Season 2 Episode 2

(After Scooby picks them)
Agent #1: That was close.
Agent #2: Yeah, I though he was going to pick the labradoodle.

Shaggy: 107 dogs in the backyard for the entire day. Like, the lawn will never be the same!

(After Dr. Phibes claws out Agent 2's uniform)
Agent #2: Dude! That is so much cooler than my regular uniform. High-five!
Dr. Phibes: No, I will not high-five. You know why?
Agent #2: Because you haven't had your tuna and milk yet?

Shaggy: Why do you call him Sparky, anyway?
Robi: Because his wiring is not properly grounded.

(After hearing a cat mewing)
Shaggy: Scoob, did you mew at me?
Scooby: Certainly not!

(After Scooby puts the kitten into his mouth)
Shaggy: Scooby! Just because you're with all your canine cronies doesn't mean you need to give into peer pressure.
Poodle: Ha ha ha! Look! He coughed up a furball!
Scooby: Shaggy, you're killing me here!

Dr. Phibes: Well, what do we have here? A disturbing little mechanical doggy with a waffle iron for a face. Oh! And he has a juicer for a foot. How perfectly random.
