Eddy: "See? Now he's making a Cockroach Kid."
[Ed observes closely, especially in regards to the notes Edd makes. Every time something is scribbled down, Ed takes careful notice of what has been written.]
Edd: [noticing Ed's presence] "Ed. It's impolite to stare."
[Ed proceeds to sniff Edd's hat and arm before making a declaration.]
Ed: "He is not of this earth, Eddy!"
Edd: [confused] "What? Is it my breath?" [He goes in to brush his teeth.]
Ed: "I saw his tail!"
