Arnie
- I'm gonna get some gum. Plain-flavored gum. (walks away)
Lulu
- Arnold, would you like something ever so sweet as well?
Arnold
- Eh, sure. (Lulu kisses Arnold)
Arnold
- Lulu, what are you doing?!
Lulu
- (seductively smiling) I'm certain I'm trying to kiss you.
Arnold
- Kiss me? You're Arnie's girlfriend, and... we're nine!
Lulu
- Oh, Arnold. You're just all too square.
Arnie
- I realized why you came here, Arnold--so you could steal my girl. And now.... now..... you're gonna pay for it!
Rhonda
- It means weird, and that's a major understatement. I mean, the boy's wearing pajamas for heaven's sake.
Harold
- And look, they have little bears on them! (laughing)
Sid
- Boy howdy, talk about embarrassing! (Arnold blushes)
