These are my favorite sketches I came up with.
The reason Brendan looks angry at Scout in the sketch when they are beat up is because Scout is always getting Brendan into trouble. Usually Brendan gets beat up for what Scout did, while he on the other hand did nothing wrong. In reality, Scout likes it when Brendan gets hurt too so he isn't the only one.
Scout is attracted to anything shiny.
Also Brendan plays the Squeezebox like Arthur did, the art of playing it being passed down through each generation of the McBride family.
Scout though plays the fiddle. "You are the first McBride ta ever play a fiddle," Brendan would tell him. Also Brendan always calls Scout "Little Goblin". Well, yes, Scout does look a lot like a goblin. I have always thought that he looked like an evil version of Arthur.
