You realize the guitars are magical, and they do magic stuff depending on the cords played.
Eh..You suck at the guitar..

You have no idea how to use the guitar, your'e just flailing your arms on it. Probably why it isin't working.. Hm. Must need someone to play it right. anyways, you carry the guitar around and get the time travelling flying van, you fly on-top of a Burger king, bust through the roof, and order 20 chicken tenders.
