Pool Shark - S2-E5
Character mistake: In the episode in which the two brothers play pool, when they meet Josh's camp pals before they leave, Josh says "Thanks Ron," but he is talking to the other character.
The Peruvian Puff Pepper - S3-E2
Character mistake: Drake says he hasn't been in Megan's room since he was five, but he brings Grammy's bags up there in the episode "Grammy".
Chosen answer: Well, she is the most liked sibling, so she can probably get more out of her parents, or get money from both of them without the other knowing, or as we saw in the Gary Grills episode she can get money from people easily by telling them all sorts of stuff.
