A guitar player comes to the doctor and complains about a serious deterioriation of his memory. He especially has a hard time remembering correct changes and is afraid to lose all his gigs. Since the doctor can't find the cause, he asks the guitarist to leave behind his brain for a week in his lab for more detailed examinations. After seven days the guitar player fails to show up, and even after 2 more weeks there's no sign of him. Finally the doctor runs into him on the street, grabs him and asks: "Excuse me, but your brain is still waiting for you to stop by and pick it up, so why don't you show up?" The guitarist says, "Well, I think you can keep it; I finally switched to bass..." Guitar Jokes [courtesy GuitarTrader.com]:
