"Ralph's Big Mouth" (aka "Mind Your Own Business"):

Trixie: "Ed, did your first day really go well?"

Ed: "It was a dark, dark day."

"Hello Mom":

Alice: "My mother is coming and you are going to be nice to her."

Ralph: "I'm going to be nice to her. That's impossible. We don't get along. We're enemies. Natural enemies like a boa constrictor and a mongoose."

"Songwriters":

Ralph: "If you can write music, you can write any kind of music."

Ed: "Oh yeah?"

Ralph: "Yeah."

Ed: "Name me one Rhumba that Beethoven wrote."

"Battle of The Sexes":

(Ed & Ralph have been having Franks and beans for three days.)

Ralph: "I would like to have a decent meal too."

Ed: "Yeah, I see that you are wasting away to a blimp."

"Without Reservations":

Stanley: "You know that this is the first time in a long time that I have been here for one of your meals?"

Ralph: "You act like you haven't eaten since."

"Without Reservations":

Stanley: "Ralph, tell me. Are there any more openings at the bus depot?"

Ralph: "No."

Stanley: "Then how do you get in the building?"

"Life Upon The Wicked Stage":

(Ralph and Ed rehearse their mind-reading act in which Ralph will hold up an object while Ed tries to guess it with the help of Ralph's clue while he can't see. Ed's eyes are closed while Ralph holds up a watch.)

Ralph: "Watch out for this, o' swami."

Ed: "What's the clue?"

"Young At Heart":

Ralph: "How am I supposed to waddle like a duck?"

Ed: "It's easy. Just walk like you always do."

"Cupid Part 1":

Ralph (to Herman): "You are easy going. You are considerate. Now what woman would want that?"

Ed: "How about Alice?"
