A little boy learning bass brings his 4 string up to his dad and says "Watch this dad!" and plays an A repeatedly. His dad says "That's great but you should probably learn some more material if you want to get better." So later on the boy comes back and plays an E repeatedly. His dad says the same thing to him. The next day the boy comes up to his dad looking very excited. He plays both the A and the E one after another and thinks he's pretty hot stuff. His dad says "That's great but you still have a lot more to learn." The boy says "I know dad, but I've already got a gig in a country band!"
