Factual error: When Josh buys Drake another guitar, he hands the shop assistant his credit card, picks up the guitar and it's case and runs out the shop. The shop assistant hands Josh his card back but Josh doesn't sign the bill, so the purchase isn't authorised.

Continuity: At the beginning of the episode, while Drake sits on the bed with his guitar, the strap falls down off of his shoulder. In the next shot its back up on his shoulder again.

Continuity: When Drake starts to lay on the couch with chips, Megan grabs the chips. The autograph on the guitar disappears.
