Don't try nothin' 'cause I got a razor here sharp enough to cut a week into nine days
Greg doesn't realize 'how important his dad is because he is mad that he won't let him play on the scorpions because he is failing math.
Watch my back im going up
Don't make me come up there and hurt you
Greg is mad so he goes to find a peaceful place to think it over.
I gave it to my son when he went into the war and it found its way back to me
Greg walked off mad at his dad but met this homeless man, that he realizes is man that digs in the trash.
These are the bad men that don't have jesus in their life and are making bad decisions and are after Lemon Brown's treasure.
Hey rag man you up there
Lemon Brown is showing Greg that he should be thankful for his family because he never got to see his son because he was a jazz musician and was busy and had no time for. So Lemon had gave his son a harmonica and newspaper and they gave Lemon what his son had on him when he died in war.
Do you really have treasure?
Greg realizes he should be thankful for Lemon teaching him how he should be thankful for his dad.
