Rosie gets grounded all because she wanted to be rich.
Rosie: Hello, I'm Rosie and today, I'm going to steal the leprechaun's pot of gold.
Leprechaun: Happy St. Patrick's day.
Rosie: Hey Leprechaun, there's a lumberjack trying to chop down your trees!
Leprechaun: Oh no! My trees! I will save them!
Rosie: Now that the leprechaun is gone, I will steal the gold.
(Rosie steals the gold)
Rosie: Yes, I'm rich! I'm rich!
Leprechaun: Damn, I don't see the lumberjacks knocking down my trees... (after realizing that his gold is gone) ...but hey, where is my pot of gold?
(Leprechaun sees Rosie)
Leprechaun: Hey you! Is that my pot of gold!
Rosie: Yes it is!
Leprechaun: Oh oh oh oh oh oh oh oh oh oh oh! How dare you steal my pot of gold! That's it! I'm calling your parents right now! (on phone) Hey Boris and Doris, this is the leprechaun speaking! Your daughter tricked me about lumberjacks and stole my pot of gold! Please ground her right now! (he hangs up) Now that my pot of gold is safe, I will put it back where it belongs.
Boris: Rosie, how dare you trick the leprechaun and steal his pot of gold!
Doris: You know you're not supposed to take money from people!
Rosie: Sorry, all I wanted to do was be rich.
Boris: We don't care! You are grounded until Canada Day!
Rosie (running upstairs): Waaaaaaaaaaaaaaaa haaaaaaaaaaaaaaaa!!
