Stephanie: (After hearing Ziggy burp) Ziggy, you promised.
Ziggy: I know, but the burp came before I could stop him. Or her. Maybe it was a girl burp.
Stephanie: Last time we had a party, the kids went kinda wild. Ziggy kept burping, and Stingy hid all the presents.
Milford: Oh yes. I remember I found one of the presents in my breadbox.
Robbie: Whoever invented high heels must've been very short.
Robbie: (Reading) "Rule #3 Don't eat with your fingers." What are you suppose to do? Eat with your toes?
Robbie: (as Miss Roberta, egging on Stingy to open presents) Yeah, that's my boy! Rip the paper! (as Miss Roberta) Rip the paper, my son. Rip the paper.
Robbie: (to Ziggy, as Miss Roberta) Release your inner burp.
Robbie: (normal voice) And now my evil plan begins.
Kids: Huh?
Robbie: (as Miss Roberta) And now the lesson in manners begins.
Robbie: (as Miss Roberta) Just leave everything to Miss Roberta and your party will be a huge success.
Milford: Oh, I love parties. And I love bacon, too.
Robbie: (Reading) "Rule number 2" (Holds up four fingers) "Always chew with your mouth closed." (Attempts to do as the book says) Hmm... If you chew with your mouth closed, how are you supposed to jam more food in?
Robbie: WHATEVER! IT'S NOT POLITE TO STARE! GIVE ME THAT!!!!!!!!!!!!!!!!
